I'm not trusting them reality tv stuff. They fake the funk just to sell a narrative for ratings.
Correction to the dude that says that musicians are hot. They are just as normal looking like you and I. What attracts are his talents. If you can sing or play a musical instrument, you already won a large part of the female population.
A guy on youtube tested out this theory. He plays his guitar at random strangers while singing before going in for the kill with getting their numbers. Obviously that he only shows them successful ones and I'm sure he gets a bunch of rejections and those are never showed as losing battles are not needed to be remembered by.
