This is really weird. All of the iTunes songs I have purchased play fine in iTunes on my Mac. Now when I go to play them on the iPod, just about every song stops very early in the song. And the stopping time varies on each song. But none of them play all the way through. And a lot of those same songs have a loud "screetch" sound at some point. Very bad when listening to a loud song. Other facts about this problem: - 99% of the music ripped from my CD's plays fine on the iPod - I'm on a G5 Dual 2 GHz Power Mac - My music library is on a USB2 External hard drive - I have a black 80gig video iPod - the same issue was present on my 2nd generation 10gig iPod Any ideas here? Thanks!
