1. Your Track Royalties: Yes—you get paid for your master recording! But not without promotion, mind you. Think streaming platforms like Spotify or selling on Beatport.
2. Composition Royalties: If you were a writer on that track, you are owed composition royalties. These come via your PRO—or, even better, via a publishing admin. Fun fact: Some artists only own the master but not the composition because they hired other people to write the song. Spotify and such also pay a cut for using your composition. And if your track gets played on radio, TV, or live gigs? More money for you. Check out more info here. 
3. Sync Deals: Your music could end up in a movie or as background music somewhere. This is called sync licensing, and it's a solid money-maker. To get started, join an agency like Bodega Sync.
4. Ghost Production! Not interested in the spotlight? Some producers sell their tracks exclusively or through licensing deals as ghost producers. Platforms like BeatStars, House Of Tracks or Pond5 are perfect for this. More info here.
5. Sell Construction Kits: Slice your track into usable samples and loops. Focus your ears on those beatmakers and producers who are always in search of new kits to use. Why not inspire them with your sounds?
6. Sell Project Files or Tutorials: Share project files or create tutorials for extra income via YouTube. People tend to love getting to know how it's done via a behind-the-scenes or masterclass, and you could monetize the videos as well.
