When selecting music for your class, you will need to find a balance between music that YOU find inspiring as well as what your class likes. I was teaching a group of downhill mtb and they really like hard rock, punk stuff (but not all of them did) but i couldn't teach to it, i did try. so i would put a bit of both which seemed to make mostly everyone happy...

remember there will ALWAYS be someone in your class who doesn't like your music or maybe even your style, just dont' take it personally...
