It's a sensitive subject. You are violating copyright.
The YouTube audio library
is a collection of music tracks that YouTube video artists can download for free and use as background music in their videos.
These high quality 320 kb / s music tracks are available royalty-free. Their use does not create a claim on your video.
You can also use music files from this library in videos that generate income on YouTube. If you submit videos for monetization using these songs, you may need to provide additional evidence to prove that you have the commercial rights to use the song in question. In this case, you should give the exact name of the musical work and state that you downloaded it from the YouTube audio library.
YouTube is a Google product.
A Google account must be opened in order to use the audio library.
The audio library can be found in your YouTube account at:
