HELP: what kind of music is this? I'm looking for similar music

here is a sample: http://www.mediafire.com/?8rzspnr56a4l2m7

I really like the background music, but I don't know how to describe it. Some words I thought might describe it are downtempo, chillout, ambient, r&b soul... but I've searched each word on youtube and found nothing close to it.

Please help.

For something similar, try looking up trip hop, which is ambient against a hip hop beat, with the "Bristol scene" consisting of Portishead, Massive Attack and Tricky among others.

Massive Attack - Teardrop
Portishead - Roads
Portishead - Sour Times
