    I am going to take a very cautious approach with deleting and re-downloading to 'upgrade' my library. So far I have done a few tests and have already found some problems, such as wrong artwork and 'remasters' that sound worse than the version I had; for example Electric Ladyland by Jimi Hendrix.

    I would recommend taking it slow and doing an album at a time, at least at first. Or if you are going to go for it and mass-upgrade everything eligible that is under 256k bitrate, make sure to tell iTunes not to delete the old files so you can restore them if you need to. If you delete the matched iTunes versions and the old ones are still there I believe they re-associate, it worked for me with the Hendrix album.

    Agreed. I've already had a few "Matched" tracks fail to download the upgraded 256 Kb version from the iCloud after deleting the original from my library. Anyone know a way to resolve/fix? Thanks.

    Hm when you say failed did it give an error message?

    I was one of those "crazy" folks to make a smart playlist based on the Macrumors post, and deleted my entire library and redownloaded everything. And not one error or file below 256k. Anything that was labeled as matched was upgraded to higher quality(if it wasnt above 256k based on my smart playlist)

    I did this without backing up, nothing and it went like butter. Although the GB taken up by all the new files was massive. I had to download a little over 5,000 songs, ate up lots of my HD space as figured!:D

    Just backup your library before doing anything. Then you are free to experiment.



    Can't you recover the original from your trash?

    Yep. "Unknown error has occurred -11111." Many on Apple's forums are seeing the same thing.

    Good luck with that. Hope you don't regret it.

    Why would I regret it? Not like I can't replace the file if one goes away I have many free or paid services to acquire it from.....I had the same number of files before Match, as I did seems stellar to me

    Some of you, and not neccessarily you(who i quoted) but so many are doom and gloom. Just do it, if it screws up, those wiser than me will have backups on TM so have fun, it's supposed to be!

    I have put countless hours (weeks..months) of effort into my iTunes library over the course of many years. Having backups is fine but reverting to them can be a nightmare once you make any changes...and the worst problems are the ones you don't know about.

    Personally I did a test of a few albums and found problems just in those. For example Jimi Hendrix Electric Ladyland had the wrong artwork (really ridiculously wrong, some parody album from some joker) and the mastering was brickwalled to death and super loud and grating sounding. And since it uploaded some of the songs and matched others, if you try to listen to that as a whole album you will have a very unsettling experience of good sound but having to turn it up louder, then suddenly the next song is blasting your ears with superloud digital harshness.

    Sounds like you are much more relaxed about your library, which is fine.

    Yes, I should've took into account how some are more fine tunes with their libraries. Well good luck to you! I hope it eventually works out for you.

    I am confused. I have a song, that when I ripped it to my computer (like 6 or more year a go) there must have been a scratch on the CD. So whenever I listen to the song, there is like a 2 second weird sound. I figured i would delete it from my library, then remove from trash. Then I clicked the iCloud download button next to the song in my library, and it has the same exact problem, and is still at 128kbps. What am I doing wrong?


    I just tried the same thing with the previos track from that same CD rip. That one successfully redownloaded at 256kbps. On the song with the problem, the very beginning of the song is the part that is messed up. Could that be why iTunes can't identify the song to match it?

    Most likely it was not matched and your original was uploaded to the cloud so all you were doing was redownloading the original again.

    I'm in the process of doing this too, although I backed up first and have just over 13,100 songs. And at first it seemed like it was going great. Did the matching/uploading to iCloud.

    Made a smart playlist with files above 96k and below 256k. Told me I had about 9000 tracks that met criteria. Began doing the download all option, suddenly told me I had about 2060 songs to "download" from the cloud. (EDIT: Likely I'm an idiot when i first was writing this. Its very likely iTunes Match only had 2060 of the 9000 lower than 256K quality tracks available on iTunes so that may explain it).

    A quick checks shows all songs still remain in my main "Music playlist" with the cloud download icon next to them (and any in custom playlists are still there as well). So I'm not sure why the other 7000 or so aren't being downloaded, perhaps I can recheck later.

    About every 100 songs or so I get a request to "sign in to your iTunes account to download" and I'll sign in then get an error message saying song such and such can't be downloaded. On some of these songs the message hangs while others download and on other songs it downloads it anyways.

    I found that if you do the smart playlist method of quickly identifying low bitrate songs after iTunes Match sync and then deleting them all at once, a glitch happens where some of the songs may no longer appear in the smart playlist. So what happens is only the remaining songs in the list download when you do "Download."

    Fortunately you can find the rest of them you deleted under the main "music" list in your iTunes and click on the cloud icon next to each one. Or you can do "Select All" for your entire music library, right click and select "Download" and iTunes automatically begins downloading all the tracks with the cloud next to them.

    So don't panic if the smart playlist after you do the "delete" step of the quick upgrade guide suddenly decreases by a few thousand songs. They'll be found safely in your main music section of iTunes for download.

    If you are going to do the Smart Playlist thing, you have to make sure one of the criteria is 'iCloud Status is Matched'. You can also also do it for 'iCloud Status is Purchased'. Otherwise you may delete things that were Not Eligible and you would just lose them. Also it's pointless to delete and re-download the ones that were uploaded from your own library.

    Here's a pic from Macworld showing how to set up the Smart Playlist correctly

    You could also start by first doing the ones that are 128k to see how it goes. Obviously in that case you would change the Bit Rate rule accordingly.

    I went through the entire select-delete-download process for the ~4000 or so songs that Matched in my library. I broke the workload up into chunks, ranging from 50 to eight or nine hundred, depending on how long I was willing to let my broadband bandwidth get tied up (other downloading activities slow to a crawl when you're getting packets from the Apple data-hose).

    Very, very few issues. It did hang up on one song the first day. And I encountered a weird issue after entering my iTunes password after a restart. But otherwise smooth as butter - although my library size has now ballooned from a relatively svelte 24gB to a ponderous 36gB.

    Some observations:

    • The only *obvious* improvement, so far, is that an annoying skip in an Edith Piaf song I'd bought from iTunes about three years ago is finally gone.
    • Did I really rip thousands of songs at such a pathetically meager bitrate? What was I thinking? Oh, yes - back in 2002 people actually cared about using an extra megabyte or two of disk space.
    • I also face a dilemma about what to do about the half dozen or so songs that iTunes Match has deemed "ineligible." Granted, some of them really deserve to go, unmourned, into the digital trash heap.
    • I'm still thinking about the 500 or so songs that iTunes failed to match. I have a vague feeling of unease about these tracks. Its not like they sound bad. And I guess for at least three quarters of them I could dig out the CD's and rip the offending tracks at 256k. But it would be a big task, with little immediate payoff.
    And its also not as if, should my computer crash or my house burn to the ground, I'd be without a good backup.

    But mainly, I'm wondering about why some of the tracks that got Uploaded didn't get Matched. It seems strange, to me, that out of the twenty million or so tracks in the iTunes Store, it could match Vic Chesnutt's Virginia, from his Ghetto Bells CD, but failed to match U2's Sunday Bloody Sunday, ripped from a US-issued War. I understand that the iTunes Store now only carries War(Remastered) and War(Deluxe Edition) [Remastered], but come on..

    I also wonder about iTunes Match, and the promise of iCloud, and the way this is going to impact the bulk of consumers around the world.

    I know the boards are full of whines and complaints from the audiophiles/digital packrats with their 60,000+ track iTunes libraries. But those people are the outliers. The 1/10th of 1%.

    I think of the dozen or so people closest to me, and how many of them are going to participate, or even understand what iTunes Match is, or how it works.

    Its going to be an interesting next four or five years in the digital world.

    I ran across this thread while doing a google search. I did not read the whole thread, so I am not sure if someone suggested this yet, but figure I would.

    The best thing to do is create a new library. Your iTunes will be completely empty. After that, download all of your matches, then you can import what did not sync.

    Yet another warning to be EXTREMELY cautious and make sure everything is backed up before deleting.

    I've been trying to upgrade a few things, just found an album where the matched/downloaded files all have the ends cut off. Downloading again has the exact same problem, looks like Apple may have corrupted files on their server. So along with all the other problems with Match, "upgrading" has the potential to wreck perfectly good files. Awesome.
