Joke aside, it is a great place to find free music. I am not surprised that it is more popular in countries I would assume does not have the same availability of streaming services.
Since I'm from Sweden I've been living the life with Spotify and similar services for years but still I've found myself go to SoundCloud to find the music which I cannot find on Spotify.
Weird how Pakistan seems to be Soundcloud central! I suspect that the advertising sales team at Soundcloud only care about the Western markets, hence I posted the US 'trend'.
