what do you guys use for mp3s

BT, eMule, Soulseek

Oink and soulseek are all that you need.

torrentspy right now... looking for oink

emule

ares/limewire and emule for the really rare stuff

bearflix .. is good ...
http://www.sideload.com/ (http://mp3tunes.com/) is also good

Gnutella network and its p2p clients are best way to grab single mp3s.

Definitely Gnutella network (I use BearShare)! Many mp3 files and good speeds.

Oink is shit hot

Basically the only thing I download is entire albums by means of bittorrent.
