It is spam, you could have put it in one forum and left it at that. Just Music are on this list, you don't need to do their donkey work for them, they seem to be managing ok as it is.

As it happens, they do carry a lot of good stuff.

With regard "Active Music Management", I hear it's the new venture of John Warwick (formerly of Prime and CPL). Materials are one label I know of that will be going through them, not sure who else they have lined up though, presumably Primate Endangered Species and some of those.
