Query: This video is dull...

I love step aerobics, but part of what makes it fun is good music to keep you moving and motivated. I couldn't get into this video because the music was boring. Instead of using stuff off the radio, they used this generic music which, although the tempo was good, I just couldn't get into. I also felt that the choreography was boring and advanced steppers will tire of monotonous moves.
