For music:
For easier-to-find stuff (recent releases, and/or more popular stuff) IRC is the way to go.
For harder to find stuff, I've been using SoulSeek a lot lately. Disadvantages are - que's can be long, and sometimes the server is down.
But if you're patient, and can just leave it running for a long time, it can be very good.
