I am currently registered with BMI and GEMA (German PRO, which is paid), because apparently BMI doesn’t collect mechanical royalties, while GEMA does. Unfortunately, I have to manually register many of my tracks with GEMA, which is a pain, as I have to keep track on which ones are already registered and which ones are new. My question is, is it worth being registered with a second PRO just for mechanical royalties, or I should cancel my membership there and just go with BMI in the future?
