The music of Rocket League, a vehicular soccer video game developed and published by Psyonix, is a compilation of electronic dance music (EDM) produced and curated by Psyonix audio director Mike Ault. It currently features music from 45 different artists, and has spawned a discography of four albums and four extended plays. The original soundtrack was produced by Ault and his band Hollywood Principle. Ault, having experimented with different genres, used personal projects unrelated to Rocket League as a base for the soundtrack. What followed was an EDM soundtrack inspired by early-to-mid 2000s progressive house music that Ault and Psyonix felt "embodied the spirit of the game." When in-game, the music is controlled using the playlist system "Rocket League Radio". Positive feedback from players, in addition to Ault's vision of a "big budget" playlist sound emulating Triple-A sports games such as the EA Sports titles, inspired him and the team to feature independent artists to be included in Rocket League's soundtrack. Ault credits the success of the soundtrack to the appeal of the EDM genre to the game's player base. In 2017, Canadian EDM label Monstercat partnered with Psyonix and began to feature its artists, and their music, in Rocket League, with multiple volumes featuring the music being released by the label.
