Puerto Ricans diffently contributed to hip hop in it's early stages but Mexicans haven't contributed anything of note but bad music.
I don't know what it is about them rapping but it just doesn't sound natrual. SPM was they're shot of having a big time Mexican rapper but he fukked himself up by fukking underage girls. Sad as this is, I'll rather hear a cac rap before a mexican.
And Puerto Ricans are just better at rapping than them. Just look at the list of dope Puerto Rican rappers compared to dope Mexican rappers. it's not even close.
