Remixes, edits and sample based tracks with paper behind them, so a set does not become a legal problem.
A DJ's catalogue is a catalogue of other people's work. Edits, bootlegs, remixes and unreleased tracks all live in a grey area that used to be tolerated and increasingly is not.
As mixes get monetised on streaming platforms and radio stations, the missing clearances turn into missing income, and sometimes into takedowns of entire back catalogues.
Upload the track, the source and the intended use.
Deed flags samples and remixes that need permission, and identifies the rights holders.
Send licence and remix approval requests as signable links, with terms and splits.
Monitor for uses of your own edits and issue licences or takedowns when they appear.
