public torrents are just the tip of the iceberg. try a good private music tracker.
get yourself an invite to what.cd or waffles.fm and you'll never have to search for music again
or yeah, blogspot works, but you never know what bitrate you're getting, which can be irritating.
there are some great forums out there too - get whole discographics on rapidshare with a single click. yeah.
then there is usenet for people who have the time to figure out how it works
