This is a friendly reminder that PROs in the USA do not collect mechanical royalties. That’s why, if you’re with BMI or ASCAP or SESAC, you should find a service which will collect them for you, even retro actively. I suppose Songtrust is doing this. You can also check MLC but they manage only US mechanicals and believe me, that you are interested more in European mechanicals.
I am talking about big mechanical royalties, including streaming and social media.
