β - You can release any song that is your original work and you have a license or permission to use all beats, samples, and vocals.
β - You are not allowed to release cover songs, mashups, non-music audio, remixes of another artist's music, copyrighted music, under 30 seconds, or songs recorded over unlicensed beats.
Songs that can be submitted for Distro will have a "D" icon next to them in your library, meaning that they were either recorded over a Distro Beat OR uploaded to the app.
βοΈ - Note that just because a release is able to be distributed, it doesn't mean that it's allowed to be distributed. Make sure it follows the guiedelines above!
If you have purchased a license or have permission from the producer to distribute a song that was recorded over a non-Distro Beat, then you can export it as an audio file and re-import it back into your library (use the quick upload on your profile page), and then you can distribute the track.
