Like others before in this post, I jumped on the Russian bandwagon.
http://www.allofmp3.com
(Online Encoding codes albums in almost any format and bitrate for you, includes ID3 tags and such)
http://club.mp3search.ru
(no tags or online encoding, but a ton more bootleg, underground, and rare albums than AllOfmp3.com)
Every album I looked for, I found on one or both of those sites. Prices around 1 penny per MB. I got a Junkie XL double CD album, 30 songs, for $1. 192kbps AAC files, too! In fact, if I wanted to pay a little more I could've gotten the albums at CD-quality, thanks to AllOfMP3's Online Encoding feature. Using a $20 account with Club, I was able to download 12 albums, all above 192-bit (MP3s)... and I still have $13 left. w00t!
I suggest everyone give them a look. Take your business elsewhere - I sure as hell am not going to pay $1.25 for a single song if it comes to that!
