What an absolute mess this is. Was super-excited about the possibility of this update fixing all the album artwork mess (and same for the iOS update)...but no....
Will not stay subscribed after the trial period is over.
I don't understand why they simply cannot allow me to add Apple Music "rented" music to my library (more important on the phone mind you) and be done with it. Why does it have to scour my music and change the artwork?! AAAARGGGHHH!!!!!
I empathize... and started my trial of AM with a blank library because of it. I tacked in a couple dozen tracks of my own stuff and a few playlists to see how it would work, on a spare laptop, having the icloud music library turned on with my own stuff involved. No thanks. I don't want my metadata messed with. I don't want sutff uploaded just because the track names don't match. Etc ETC. So I'm just going to have Apple Music stuff in that library going forward.
The very very good: so easy to discover new stuff that I like. I am keeping my Apple Music sub after the trial expires. I'm not a big fan of streaming, so to me being able to download choices and enable offline use is really great.
The good: I'm going to devote an iPod touch to Apple Music, and one iTunes library on a spare laptop. I will be using it mostly to determine if I want to own some of the stuff I rent. When I later buy some of those ithings onto my main iTunes library on my main laptop, then I can mix those purchases with my other stuff on other devices to my heart's content. To me, being able in this way to "preview" entire albums of classical works or whole tracks of pop, jazz, blues etc. stuff makes the monthly sub to Apple Music worth it. There's no way I can figure out if I like an opera or symphonic performance based on track previews. I have even regretted purchases of plenty of non-classical tracks when the preview was great and the track... hmm, not so much. We've all been there by now. It was one of the reasons I went for Pandora. I do like Apple Music better.
The bad: I find on my experimental spare laptop setup that I'm unhappy with the increased complexity of my iTunes views of "apple music, apple music version of my itunes-purchased music, my ripped music (uploaded)..." when I have icloud music library turned on (plus decide and then remember if I have selected offline only or all music views at a given time. Then shift to playlist view... "apple music playlists" "my playlists" and I didn't get around yet to find out what happens to Genius lists I've kept in the past because I'm afraid to experiment on my main library on my main laptop! This kind of separation by "Whose Is It?" is not how I like to deal with my music. It's artificial. It's almost as bad as having to remember if I bought a digital book from Amazon or Barnes & Noble or iBooks Store, so I can decide which app to launch. I lose my temper at least once a day launching the wrong app to look up sometning in a purchased reference book, or to resume reading a novel. And so now do I have to remember that I have a playlist of Mozart symphonies among my Apple Music playlists? Will I be looking for that playlist among the playlists of my own Mozart stuff? Will I be annoyed when I finally find the thing? Yeah! Bet the ranch!
The really bad: I am completely not interested in having ALL the same playlists on my laptop and my mobile devices. Are you kidding me? I must have over 400 playlists on my main laptop. They serve all kinds of different functions. They're lists for devices. They're seasonal. They're reminders to play newly purchased stuff or stuff that hasn't got much play or stuff I want to give to someone or stuff I want to archive and delete. Or they're playlists of audiobooks so I can keep track of where I am in those more easily on mobiles. I folder some of these lists on my laptop, of course. Well even that way I certainly don't want all that stuff on any, much less all, of my mobile(s). The global approach of "everything on all your devices!" just doesn't work for me. In fact it's the antithesis of how I use my mobiles and my main libraries. I tried messing around with folders but realized those are all global all the time too, and so that's not for me. I have to leave my main libraries out of this whole deal and use Apple Music separately. And I can do that.
The annoying: The bandwidth of getting your own stuff involved, sheesh. I understand the licensing issues and their desire to prevent your burning combined playlists, but really there must be some other way to protect the artists and labels' interests. Plus I kinda wish they wouldn't bring in the whole purchased items thing anyway. If you have a large collection of iTunes Store purchases then it's highly unlikely you want even a view of it all cluttering up your take on what's on your mobile device. I mean after awhile you wonder how much space is being taken up by just showing you an entirel library of stuff you don't want to see much less download onto that device. So again, that's not for me. Apple Music is going to be a separate experience: listen to something, like it, download it, keep it as long as I want while I subscribe, so listen some more, if I like it enough to want to mix with stuff I own, then go onto my main laptop iTunes library and buy it there and mix it there, or pick up the CD and rip it there. Period. Forget all the matching and uploading. I might make an exception here or there, but it won't happen on my main libraries on my main laptop. It will be on the spare and on that dedicated iPod touch.
Bottom line: I reallly like Apple Music, and having it on mobiles or also on iTunes on a laptop. But I can't deal with the hassles of using it in an integrated way with (apple music versions of) my own stuff. The restrictions, the segregations and the globalization of choices about playlists, foldering and content on board are major detractions for me.
