    It really slows down the sync process, wish it would only do it periodically.

    Agreed. This never happened before ios5. Is new information being synced? And why is it always for 233 songs only (in my case)?

    Does anybody know ANYTHING about this?

    This could come down to differences in the Music app, which replaced the iPod app.

    Same here. I rarely use it so I've now turned it off in iTunes.

    I unchecked Genius in the General section of iTunes but the data still syncs with my iPhone. Is there a different way I'm supposed to turn it off?

    Store menu > Turn Off Genius

    There is no "turn off genius" option in Store

    What do you do if there isn't an option to turn off Genius? I tried one supposed fix by turning off iTunes Match, but under Store there isn't an option to turn off Genius.

    i'm getting this also. seems to always sync 91 songs and always the same songs. the sync completes ok (no hangs etc) but i wonder what exactly is being sync'd and why the same quantity/tunes each time?! :confused:

    does not matter if genius is on or off on the left sidebar, i still get the syncs

    Sucks for you guys, it only does this for 20 songs for me.
    The solution to the problem? There is none. Apple needs to hire some better developers.

    I get this for 368 songs. iPhone 4S on iOS 5.1. It must be a bug. For me it's not a big deal though it takes no more than 15 seconds to process the "Genius data"

    It definitely seems like a bug in the way genius data is stored on an iOS music database.

    Note that the initial genius sync could take a while so let it run once but if you keep seeing a portion of your library syncing genius data then you are experiencing the bug.

    It looks like it's caused by having two or more songs with the same name in your library. They do not have to be exactly the same but one has to at least begin with the full name of the other. The songs do not have to be from the same artist. At least one of the songs needs to have genius data that is trying to sync with a device.

    For example here are some of the songs that have multiple similarly named songs in my library. These will cause one of the songs in the set to have continuous genius syncing:

    Novocaine for the Soul by Eels
    Novocaine for the Soul (Live from Hell) by Eels
    Novocaine for the Soul (Moog Cookbook Remix) by Eels


    Icky Thump by The White Stripes
    Icky Thump (Live) by The White Stripes


    Shoot to Thrill by AC/DC
    Shoot to Thrill (Dummy audio track I recorded and gave same name as another song)

    I'll be submitting a bug detailing this. Submit duplicates of the bug so Apple will pay attention to this.


    Note to iTunes Match users. It also appears that after an iTunes Match update (adding new music) iTunes will perform a sync of a larger section of the Genius Data information. This is likely due to the fact that iTunes Match and Genius are tied together and perhaps doing an iTunes Match update brings down slightly altered Genius Data.

    Yes, I'll agree, it's not a big deal, but it is extremely annoying.

    Please fix in iOS 6, Apple!

    Installed IOS 6--Syncing Genius Data still an issue

    I do have a few songs with nearly the same title, but I'd hoped that IOS 6 would stop the continuous syncing thing. I guess it's not actually hanging, so maybe it's not the same problem others were describing, but I don't know what good it is supposed to be doing me to have this information synced at all.

    Confirmed to be still present in iOS 6.0.1. It is pretty bad in my case, it syncs the data of about 1200 - 3100 songs, sometimes a bit more if I haven't synced in a while.

    This is really bad I must say.

    Any other way to avoid this without have to turn it off?

    I'm looking for a fix for this as well. Its annoying when it takes forever to sync the data for 2000+ songs.

    Looks like that doesn't happen in new iTunes (latest version)

    I'm using iTunes 11. My iPod is syncing genius data. 6,970 songs. It's going to take about 20 minutes.

    It's stuff like this that makes people switch to Android devices, Spotify, etc.

    Edit -- might take an hour.

    Happening to me as well...

    OS 10.8.2
    iTunes 11
    iPhone 4S

    On first sync, updated the whole library's genius info. On second sync immediately after synced about 55% of the library. Third sync immediately after, nothing.

    We'll see going forward.


    Next sync on 12/7, updated 50% of the library's genius info and on the sync immediately following updated 50% again.
