This is my domain.
If you're looking for anything upbeat, go on kazaa and do a search for DJ Irene (AWESOME electronica 'gay bar" if you will), To Kool Chris (really cheesy, a shitty person, but good workout music), Paul Johnson, or Dj Bam Bam. John Digweed is also a good choice. Essentially, you're looking for either "euro" "house" or electronica- not trance.
** Note- in this case I'm condoning Kazaa b/c these would all be tracks purposely loaded onto the internet by these djs- you're not stealing from anyone.
