did you ever find out who the artist and song tittle was? i've been looking for this as well. i heard it way back in 2001 but still have not been able to find it. i did however find this song:

IAM - l'empire du côté obscur

but i don't think that's the one i remember. i specifically remember the Imperial March being used as the beat
