Heavy but melodic
George Acosta -- heavy but melodic -- some not so heavy
Paul Van Dyke -- easy listening trance to slightly harder
Robert Miles -- rather easy listening
ATB -- slightly eastly listening, melodic, and heavy at times
paul van dyke & atb are very good choices..
i'm not sure about dj tiesto, most of the stuff i've heard of his is really heavy and pretty much progressive, i dunno, i guess it depends on what you consider melodic n shit if you're looking on kazaa though i got some so you won't come back empty handed
