step 1: no music on iphone, itunes match turned on
step 2: download already owned music from icloud onto iphone
step 3: buy new music on iphone or itunes, downloads to both mac and iphone
step 4: delete the new track from itunes on mac (but not from icloud) but keep on iPhone
step 5: try to sync iphone... issues begin
I do have the most up to date versions of iTunes, Lion, and ios5
more elaborate description:
So a couple of times I have deleted music on my itunes, because I want to store the tracks in the cloud - not on my hard drive.
It seems like each time I do this my iphone has trouble syncing. I've read all the comment threads and a lot of people have similar issues but fixes seem to happen with voice memos, which I do not have on my phone.
What i did notice this last time is that ~150 songs were on my iphone, but not showing up anywhere in the music app. I noticed this as I did a restore from backup and my itunes app on the iphone started automatically downloading a lot of tracks, yet when they downloaded they did not show up as downloaded in the music app. I would actually have to download the song again from the cloud on my iphone to listen to it (so I had multiple copies of songs on my iphone [visible in the iphone->music folder on the sidebar of itunes when iphone was connected to itunes], yet only one copy would show up on the iphone music app).
Does anyone else have this problem? I'm not 100% sure if this is the root of the problem I am having, but it seems to be the common denominator.
