The YouTube Content ID system is flawed. The algorithm can’t tell the difference between two different songs when they both have the same instrumental/beat. So you are unable to use Content ID for a leased beat.  I know, it sucks. This is something they should really fix.
This means when releasing a song with a leased beat through Distrokid, Tunecore, CDbaby or any other digital distribution service, you can’t enable Content ID. Please disable Content ID when distributing your song through one of these distributors.
This is the same for all beat licensing websites including Beatstarts, Airtbit and TrackTrain because it is an issue with YouTube’s algorithm. None of these sites allow you to use Content ID on leased beats, simply for the reason that it creates mis-identification of songs and causes problems for artists. So this is an industry wide problem.
To protect those that lease my beats from bogus takedown notices from other artists abusing the YouTube Content ID system, I’ve already assigned YouTube Content ID to all the beats on this site, so you are protected.
This appears to be the best way around this issue at this point in time.
