At our anual school demo they played the Soundtrack from "Rocky". I'll tell ya I get pretty pumped listening to "Eye of the Tiger" before a workout. As far as doing forms, well I don't really do them to music or anything.
Believe it or not, I just did my carenza last night to a song called "Breath" by Swollen Members featuring Nelly Furtado. Although not my usual workout music, it is high energy and positive, so it fit my high speed carenza quite nicely. Normally though, I listen to techno, trance and deep house...stuff without lyrics, but high energy, altered state kinda stuff.
