This is great for the class as well as the instructor, I burn a CD. with about 20 or so generic cycle song (music I am familiar with) some long songs, some short, some fast, etc. At the beginning of class I pass around a hat with numbers writen on slips of paper, and randomly select people in class to give a number, that being the song that gets executed. This keeps the instructor on their toes, as for the class you can blame any bad selections on them. Oh yeah make sure you write the songs down on something in numerical order. Enjoy
