I'm so happy to see so many people mention Hotline in here! Aahhh the good ol' days :) Indeed, when Napster came along, it wasn't too surprising to me .. that is, other than the true p2p nature of it, rather than server/client/tracker. That was indeed awesome. But there was also a bit less accountability so you got a lot of sketchy/crappy stuff, whereas hl servers (and users) had somewhat of a reputation to uphold (IMO).
