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:
…Anyone? Yes?
Well, a girl can hope.

I’ve managed to slip the Thundercats theme tune and Can’t Hug Every Cat into my class playlist, along with lots and lots of awesome ’80s. REALLY looking forward to my lesson just before xmas, as then I can really lay the cheese on thick. 😀
Haha, we rarely play music in class, but I more often than not hum the Fraggle Rock theme song when training 😉
80scartoon.co.uk. More awesome theme tunes than you could shake a white mouse with an eye patch at. 😀
Looks like this is the more US-focused version.
I almost spit out my coffee I laughed so hard reading this post! I play my Pandora radio at the gym and one day I forgot to change from the musicals station I listen to in the shower to the Rancid station we usually play. Everyone was jumping rope, hitting the bags and generally warming up when “Lonely Goatherd” from Sound of Music came blaring throughout the gym. It was awesome and embarassing at the same time.
We’ve played with some really fun stations on Pandora, including Kid Cudi, Queen, The Pixies, Black Flag and most recently, Dubstep. I hate those two songs you mentioned above, so the rule is no lame ‘MMA’ music.
