I'm a massive fan of techno/trance/a bit of hardcore music. Well, here are two songs that I found not too long ago and now I can't get enough of them.

(1) is a tune from REDALiCE called Cross Breeding. The artist is Japanese, and he (yes, a "he") does this tune very well. Listen to his mix of Motteke! Sailor Fuku as well, very good listening.

(2) is called Miss You by MINAMOTRANCE. I don't have any other details about them, but the song is very catchy. So, if you're a fan of this music just as well as I am, then these two are easily REQUIRED listening. Yes, I know there's gameplay footage as well, but hey, listen to this tune, AND watch said gameplay from Suzumiya Haruhi no Gekitou Craze (a doujin game).
