most music sounds good on shrooms I think. I prefer it when there are djs and a group of people dancing, it gives you an outlet the novel feelings you may be having, and there's something special that is created by the interactions betwen you, the dancefloor and the djs.
If you're at home however I'd highly recommend 'Black Foliage' by the Olivia tremor Control it's basically the soundtrack to a trip. Starts out joyous and uplifting, before slowly disappearing into itself and then reappearing in strange, time-distorted projections. I can't really describe it that well, but it makes perfect sense on a trip... if you can handle the journey that is.
