Sorry to hear Swim...Crowquill did it!
Oh and tdoc I have 20gb on my ipod and it's meant to hold 5000. I've used about 15 gig and I've only got about 3000 songs. It depends on length. All those long prog songs you have will count for about 3 or 4 songs in ipod language. And yeah, it's probably less when on the computer as moses said, about the compression rate and all.
