Roblox is a game-creation engine, first released in 2006, that allows players to customize their own sandbox worlds, create mini-games on multiplayer servers and enjoy a second life online as square-shaped beings called Robloxians.

In 2020, the platform spawned its own music genre — robloxcore. Mostly made by young teenagers, it’s a strain of chaotic, profanity-laden rap that’s overloaded with frantic sound effects. The name comes from the fact that many of the artists under this genre uploaded their songs to Roblox itself allowing people to play them in different games, spreading their music around the platform. Artists that have popularized this genre are lieu, d0llywood1, and 5L, to name a few.
