quite a few services out there.
It does occur to me we might be low-balling our music by going through these services. And it does occur to me we should license at least some thing via non-commercial-use Creative Commons licenses. That sounds like a band discussion which will take place over french toast or waffles.
So we might want to be selective with whom we license commercially.
And note too that the link to the above EM article is just for and about publishing rights. There are other rights which will be addressed by another post at another time.
