I mistakenly received a check from SoundExchange for royalties from 2009. Lots of errors (over 70) in the report due to grouping many of movie soundtracks under the same artist name. Notice how all of the artist names are given as MT while the track names are "XMSDTK-NP-MTS (MOVIE TITLE)". The dollar amounts vary greatly with the most going to the Star Trek soundtrack. Just a couple of typos can cause massive delays in payments. If I never had signed up for SoundExchange, I'm not sure any of these errors would have been discovered. And that leads to the question, why don't more places require/support ISRC's.
