As I have stated before, music is primarily subjective. An out of tune instrument is simply that, but otherwise just as beauty is in the eye of the beholder, music is in the ear of the listener.
That being said, there are certain songs in relation to kettlebells, weight lifting, MMA clips and youtube videos that I would be pleased to never hear again.
Bodies Hit the Floor by Drowning Pool
…Yeah, that one.
Also, Down With the Sickness by Disturbed
…those are really the two prime examples that I can think of
What I hope someone, some day puts as the soundtrack for one of those videos:
Well, a girl can hope.
