Lil B is probably fine, but he is the biggest name I recall coming out of SoundCloud. He blew up all over the 2010s, he was the Kanye of Cloudrap too because he took dressing styles and changed it all up similar to Kanye.

Shout out to lil b and those parties at Berkeley he would perform at in ‘12, ‘13.

Those were the golden sound cloud years.

I was big on tumblr, but he wasn't my style of rap, but I respect him for what he was able to pull off.

There's a few big names: Post Malone, Billie Eilish, Lil Nas X, Khalid, Bad Bunny

Thankfully the only artist I listen to on there has been known as Bryce from the suberbs for two decades:

This Kevin was still quite impressive
