Music and programming, am I right?

I know that it's better to not listen to anything, but some people like me are addicted to music.

I came to the conclusion that if I'm listening to rock where the main singer is a baritone or bass(or the music is , like Joy Division I don't lose my concentration) but on the other way, if I'm listening to something were the singer is a tenor, then I'm fucked. That's also why probably the popular music generated by males are usually by tenors, it alienates the mind of the listener.

So when you are going to do something serious or want to have a better productivity while listening to music, don't listen stuff with high notes, believe me, it works.
