I don't have a good suggestions to make, but I will say, if I hear Sweet Caroline one more time, I might snap...
Just saying
A wide range of music should be selected though, from classic rock tunes (Living on a Prayer was a good one) to pop songs (when Baby comes on, I'm confused if I'm at an FRC competition or a Justin Bieber concert). The only issue I see this year is not having a wide enough variety of music. I can only "teach someone how to dougie" so many times before I'm begging for a new dance song.
