If you have been following some of the US music trade news this year you might have seen press releases from a new performing rights organization called Pro Music Rights. They've got a pie chart graphic claiming to manage a catalog of 2 million songs. This would make them the third biggest performing rights organization in the USA, after BMI and ASCAP. However, you can download a speadsheet of the catalog from their website, promusicrights.com and it tells a different story.
Firstly, at the start of November 2018 the total amount of song titles is 1,921,376 which is 78,624 short of 2 million. On closer inspection, 1,920,742 are fake, with artist names such as BRASHCHRIS1NOTES, INSNARSTAFF, RUBATOTON1022, SCONTHEZZY485, LARGOMAN5614, BLOKEPLAY and THEJRAFFQUAVER. That leaves just 634 real titles.
It looks like a scam. Don't sign anything with them.
