I was playing music on iTunes and one of the songs I was listening to just skipped through - iTunes started skipping, 30 seconds or so at a time, through to the next song. It started to happen around halfway through the song, although exactly where is unclear. Repeatedly pushing the cursor back to where the song was before the skipping starts seems to help, in that the songs only starts skipping again a bit later. The one thing that's changed recently is that I turned on Genius. In fact, when I turned Genius off, the issue seemed to be fixed, until it happened again. I managed to make it through most of the song, though, but the next few songs all started skipping through right from the beginning. It's now happening with every single song I try playing. I hope Genius didn't actually damage the MP3s; I have no idea what it does. All I know is that my iTunes is officially unusable. Quitting the program and restarting did nothing. What's going on?
