Whenever I wanna play music on my iTunes, it stays at 0:00 ..... I've tried everything so far. I can't even go on youtube and hear the music. Yes, my volumes up, everything is plugged in, I went to system preferences and checked the sound, everythings fine. I re-installed iTunes, nothing happened... I can still buy songs and it goes on my iPod... The I have is an iMac G5 (tiger) and yes, I updated iTunes and the rest of my updates. Can someone please help me? I'd greatly appreciate it!!!!
