I used to have a MP3.com chillout station, but for some reason or another I deleted it. Nevertheless, I do still have a whole bunch of songs that I think are good, that people can download from MP3.com. These are some of them:
Argon Light - Planet Bliss (my fav. PB track)
Input: Digital - Planet Bliss
*In fact, many of Planet Bliss' tracks are good*
A Dream As Memory - Tycho (You will have to search around older MP3.com stations to d/l this one, but it's worth it)
Catalonia Sundown - David Ewen
Kansas Kids - Northcore
Lime - Messier 87
Mr. Flux - Machine Love
Phere (remix) - bitstream dream (also, another good artist)
Connected - Audioplacid (a GREAT track!)
What You Gonna Do?! - ETNICA
Don't - Trancenden
The last two boarder-line being chillout, the ETNICA track having strong funk tendencies, and
Don't definitely contains a little blues/soul but still is classified as triphop.
Hopefully at least someone will take the time to check out a few of these tracks so my list was not written in vain.
