You're in luck, I really don't want to clean the basement tonight. I wouldn't recommend downloading music, but if you do, preview each song fully. There are a lot of crappy or intentionally altered copies out there.

Unless you have a two steppin crowd I would use the country sparingly. Pick the tunes with a heavy pop/dance beat (like Any Man Of Mine)It's too hard to do the stand around in a circle and beebop dance that most of us do.
