Its music recommendation time for..

House and trance
Recommend artists or just songs and anything you regard as high quality.

^ This guy knows what hes talking about..
All the commercial trance stuff is garbage.. (Paul Van Dyk, Gatecrasher, Digweed..) Don't even bother with it.

As for House, Im assuming your not talking about that "muzak" they call house these days..
Try stuff from labels like Prescription, Traxx and DJ International, Djaxed-up-beats,(Chicago House), Mahogani Music, etc..
Thats all REAL quality house music..

KMS and other early detroit techno (transmat, etc) might be what your looking for as well..
