hi - i've have my ipod mini for just under a year and all has been great up until a few days ago. my mini has over half a battery charge left, is NOT on shuffle song mode, yet refuses to play. instead when i press play the screen randomly shuffles thru song titles (probably a good 15-20x) and then plays one song at random. i stop it and press play again and it does the same thing stopping on the same song. i have recharged completely and it plays fine for an hour or two and then does the weird shuffling thing again. any tips?? thanks!!
