You are free to use my music in your YouTube videos or streams, however, due to current policy and several complicated factors, including licensing, your video will probably get a copyright claim, meaning a part of your revenue will be taken for using the music (for using the music recording and/or for using the music composition my covers are based on).

I am the creator and sole owner of the recorded tracks (it's the ℗ symbol in the copyright world), however, I'm not the author and owner of the original compositions my covers are based on, and the rights to the latter are in the hands of music publishers and entities responsible for collecting royalties.

Do not reupload my music anywhere, and don't make extended/remixed versions (like nightcore) using my sound recordings. My music is protected by copyright law and you risk potential legal actions.
