i almost cant listen to anything that isnt like calm or trance like. i have my favorite artists, but moreover, favorite songs. here are a few in my 7024 song collection
The Doors - The End
Nightmares on Wax - Tha Journey
Alan Parsons Project - Eye in the Sky
Bob Marley - High Tide or Low Tide
Orbital - Halcyon & On & On

and, the very best "song" ive ever heard to chill to
Pure Moods - Indian Chant
words cant even explain this song... you must listen to it... its moving.
