I'm using ubuntu 12.04. I recently hooked up my iphone to rhythmbox. I pressed "sync with library" in the tab in my iphone. It did what I told it to, but now ALL my songs are trash in my iphone and rhythm box. When I click on a song in my iphone or rhythmbox, I see the album artwork for half a second, and then it continuously skips from song to song, my iphone thinks all the songs are gone, since three GBs are missing, but the songs look like they are in my music app.
What happened and how can I reverse this?
