I listen to anything with real instruments/singing for the most part. This excludes most pop, and all rap. That said, I'm a country fan 110% and recently that's most of what I listen to. Oh come on, I live two hours east of Nashville, what do you want?
But that aside, for competitions, techno and some classic rock is the way to go.... and it's not a FIRST competition unless they play Cotton Eye Joe at LEAST once
