For me this depends on the time I have been "rolling".
I tend to take pills instead of MDMA or if I can get my hands on some pharm-grade MDMA or pure MDMA, I will also get myself some speed and ket and make my own bombs. This results in a much speedier and trippy high.
So when I start the night and am just coming up, I prefer something like Tech House as I like the fact it is a little slower and has more 'bleeps and stuff'. As the night moves on I like to move to hard Techno for that extra bit of speed, the 'swings' and all the kind of distorted sounds. Towards the end of the night, I like to finish it off with Minimal as this is a nice way to slow everything down and kind of chill out at home with friends with a few drinks and plenty of NOZ (nitrogen oxide/laughing gas) as everything wears off and the night comes to an end.
If I'm just on MDMA, I'm perfectly happy with a mix between Tech House, Techno and Minimal but prefer there to be more Techno than anything else.
One thing that makes me quite different to most is if I am just on MDMA, I really don't think Drum and Bass is something you should be listening to. It's far to fast and disagrees with the 'floatyness' of an MDMA high. Just my preference but I'm certain I'm not alone with that line of thinking.
