Sweet Workout Music

I know there was a thread about this a while ago, someone was asking about techno/trance type of music to workout to.

I just recently found out about the group "Scooter" they have techno/trance type of music. And it's some of the best shit I've heard! I downloaded shitload of their songs, it is great workout music for those guys who like this kind of music.

If there are groups you know of that are VERY similar to Scooter, let me know!

Some of my favs by Scooter:

Nessarja
Posse (I Need You On The Floor)
Ramp! The Logical Song
Fire
Devil Drums
I Shot The DJ
Move Your Ass
Weekend
