Seeing Rich Brian, Trippie Redd, Joji, Kris Wu, and Baauer's names on a song together is crazy for a lot of reasons.

First, it shows just how far Rich Brian has come in such a short amount of time. With each day he takes new steps along his career trajectory from meme curiosity to legitimate artist with a very bright future. After shedding his "Rich Chigga" moniker that he admitted was "a mistake" and "a fuckin corny ass name" on New Year's Day, he's attached his name to another quality, high-profile song.

Hearing Joji and Baauer on a song together is pretty nuts when you remember Joji was the one who started the "Harlem Shake" trend back in 2013. The song also represents another smart move in Kris Wu's road to respectability in America. And, of course, Trippie continues to ride his incredible 2017 run into the new year. Pretty crazy to see how far all of these guys have come. Listen to "18" below.
