When I'm listening to music on my iPad, it doesn't play de right one. For example, if I click on "hotel California" it will play "viva la vida". I've shut it down and power it on but it still does the same. I even reset it by clicking the home button and the power button, but still no results!
The database files on the iPad have probably become corrupted. You will have to remove the songs from the iPad and re-sync them from iTunes to re-write a fresh database file. It can easily be done by unchecking "Sync Music" in the iPad's sync settings in iTunes, sync then re-check it.
