What sets MusicGen apart is its ability to be “steered” by uploading existing songs. This feature allows the AI to gain a better understanding of song structures. Felix Kreuk, one of the developers behind the LLM, shared samples on Twitter showcasing how MusicGen can take classical compositions, like Sebastian Bach’s Toccata and Fugue in D Minor, and add drum beats and 1980s-style synths to create a more upbeat rendition.
