You might want to specify what you like so people who like similar stuff can give you better suggestions.
If you like dance or electronic music, you might enjoy BT - These Hopeful Machines.
Look no further than your username for another suggestion: Robert Miles has some pretty cool stuff. I still pop in Dreamland as some decent chill music once in a while.
Some of the best trance I've heard on one compilation: Thrillseekers - Nightmusic, Vol. 1 - http://www.amazon.com/Nightmusic-Vol-1-Thrillseekers/dp/B000BYR9WC
I keep listening to it, and it just doesn't get boring!
Try some Dreadzone and Happy Mondays.
Damn, Youtube must have banned it in certain parts of the world...
Hope you can find it somewhere else.
Edit: You might be able to listen to the sample at Amazon at least?
