I received an email regarding the above. It's not spam as I've replied to the feller who sent it from Sirius XM.
I have to confess I know next to nothing about SoundExchange royalties and the like (which this agreement seems to be about)
I asked the feller if it would cause problems with my stuff already being up on iTunes etc. via CD Baby and IODA, he said it wouldn't, but I didn't really understand what I would be agreeing to ? I imagine any royalties would be a pittance, but I don't want to sign anything that could cause problems down the line.
Anyone know more about Sirius XM and such things ?
