Uploading your songs to YouTube Music will not create conflicts with YouTube’s Content ID system.
YouTube Music works as a subscription-based streaming platform, similar to Spotify or Apple Music, where listeners can play your tracks.
Content ID, on the other hand, is YouTube’s tool that automatically scans uploaded videos for your music and enables ad monetization on those videos.
Music you send to YouTube Music via eMastered won’t be added to Content ID by default.
If you want your tracks included in Content ID, you must also opt into eMastered’s optional Social Media Monetization release extra.
