This could be another indicator of your levels of testosterone, metal for high testosterone guys, and pop for soy boys. Personally I don't mind it either way, soy boys have some very good music too.
In fact, I can side with the soy boys here because it is nice when the video starts and the girl starts dancing in a any way. Girls dancing has always been a stupidly effective way to make girls overpowered because it is hard to resist those hips moving to a beat.
It basically indicates that she is ready for sex, and that she wants it, so the subconscious interprets that the girl is ready to be impregnated which translates into an instant boner because your body reacts.
In reality she won't get impregnated because in this site she will get fucked in the ass, not the pussy, and she probably won't enjoy it as much because there is not clit in the anus either, but that's OK because we are all here to enjoy seeing the girl getting fucked in the rectum, and as long as that happens it is all good.
Besides, just to counter the point a bit, metal is dance-able too. Just ask all fans of the glam, arena, hard rock, hair metal of the 80s. Some of those songs still play in strip clubs around the world. This music was before my time, but music is timeless anyway.
Like Mötley Crüe:

For example Judas Priest. Here is Judas Priest with gay singer Rob Halford who is awesome:
