How popular is rap now?

[Deserted]

Hi all, was looking at some Khmer music on ty the other day and noticed some local rap artists and was pleasantly surprised by one of the tracks. Anyway, I clicked on a playlist and noticed that there were a lot of different artists and tracks. Mostly local artists and some of them kids still. Is it an underground movement or has it really taken off? I don't see it being played that often but I don't know.
