You shouldn't do anything! [Merlin] Symphonic Distribution is the new company we use to power our Content ID and YT Music Feature. When a claim is placed, ads will appear on your videos or other videos that use your music and we will then receive the statement from these companies and pay you your cut of the ad revenue. The reason it is on behalf of: Terrabyte Music is because that's the label that is setup with Symphonic. Do not worry, you will still be credited and earn the revenue.
