Until this gets too big, I'm going to keep including the music I've been buying lately here....

Faithless (Techno/Trance/Dance)	While I really enjoy all of their stuff, the first album, Reverence contains the songs I fell in love with. (Probably cheaper to look in a used store for this, if you are interested...I've seen them go for pretty cheap since no one really has heard of them.)   I recently got The Testimony, Chapter One singles box set.  Some excellent mixes of their songs are on these singles and you will enjoy listening to them as much as the album.  (Most of the CDs are over 20 minutes)
Rabbit in the Moon (Techno/Trance)	These guys are great.  Rabbit in the Moon remix songs by artists like Sarah McLachlan, Garbage and White Zombie.  They have taken some of their remixed songs and made this compilation of great techno/trance songs.  Great to study, read or computer to.
Eddie From Ohio (Folk/Rock)	cos introduced me to EFO as he introduces me to most new music.  He hands me a CD and tells me it's cool.  I listen to it, and more times then not, it is.  EFO's latest album, Looking Out the Fishbowl, is out and great!  First time listeners should go for Portable EFO Show.
Salamander Crossing (Folk/Bluegrass)	A folk band from Amherst, MA.  I grew up there but didn't get to see them live 'til I came to Portland, OR.  These folks are great, I would recommend their first and self titled album for a first listen. (Another artist introduced by cos.)

To set up a page like this for yourself, go to CDnow and look for information on their affiliates program. It's very cool!
