I am running iTunes 10.5.2 (11) on Lion 10.7.2 and I have an iPhone 4. Several times now I have created a playlist on my phone and the next time I sync to my mbp, itunes blows away the playlist on the phone. I had expected that iTunes would copy the playlist to the computer. Is there a way that I can prevent these playlists from being deleted?
It sounds like you have 'playlists' ticked in your syncing preferences and that iTunes is overwriting your playlists with no playlists as it syncs from the computer.
First thing to do is to check that Playlists are not being synced under the device in iTunes and Music. Uncheck "sync playlists" and try again.
- Create a new playlist on the iPhone and add some songs to it
- Connect the iPhone to iTunes
- From the Summary tab in iTunes, check the "Manually manage music and videos" then click "Sync"
- The playlist should appear under your iPhone entry in iTunes now
- Now uncheck the "Manually manage music and videos"
- Navigate to the Music tab and check "Sync Music and Entire music library"
- Sync again and the playlist will appear in your iTunes library.
I am not sure whether this is some kind of bug but it worked for me by following the above instructions.
Otherwise iTunes would delete the contents of the iPhone-created playlist upon sync without following the above steps.
This drove me mad when I inadvertently deleted all my playlists...
Unplug iPhone from PC. in your iPhone: Go to Settings - Music - then Turn off iCloud music library.
When you reconnect your iPhone to PC - should now be able to select the music tab under your mobile device in iTunes and select which playlists you want to sync. voila! they should be back on your trusty phone.
