Content ID Music
Declan DP's Content ID Music works like traditional licenses, just without the payment. You simply locate a license to use the song on YouTube, copy and paste it into your video description with a code that's unique to you and dispute the claim. After a few days, the claim will be removed (as long as haven't broken any rules) and that's it! You still get to use the music for free whilst keeping all your revenue but the music is protected against false claims!
