The latest fad going around is the host of MP3 search sites that are cropping up all over the place. Most of these are built off Google searches and can be hit-or-miss. But they're pretty useful for finding that rare track you always wanted, but couldn't find ...
A few examples include Skreemr, MP3 realm, FileWin and Pleera. Then, there are other chaps like this feller.
The Internet is never boring, is it?
