practicality

I really want to like my Linguistics course - the material is interesting, and the prof is actually pretty good. Unfortunately, my TA for the tutorial section is terrible. She's spends the entire period going over needlessly long answers to simple questions, I think in part to cover the fact that she doesn't know what she's talking about. And she does this instead of giving us important information about assignments. I'm starting to dread Fridays, and it's too late in term for me to switch to a different tutorial section.

And entirely unrelated, but can anyone point me in the direction of some good happy-techno? Something along the lines of DDR stuff like Candy Star (DDR recs are actually okay, too, as I haven't heard all of it, it's just that the tracks are short)
