Stu, that's kinda what I was thinking, but I don't have the technical know-how to really tell. It's not happening between all songs, but I'm sure it's just when the buffer is running low. Inserts do funny things (like make little pauses in audio) as they play with the memory.

I have one 60GB drive and one 80GB drive. I think they require more power to spin and might also explain why I'm more prone to getting a "warm boot" (5 seconds) reboot in car with a battery icon sometimes..

I should have used HiJack to get a temp reading... Maybe it's time to turn on the "hi temp shutdown" in HiJack?

Good luck on your freeze too!
