SGOTI: the theme is GMZ by Scott Altham

It is a shame about CCHits' demise, as it as such a good project to be involved in.

As far as other CC music sites are concerned, there is Jamendo and the Free Music Archive, but they both have their own quirks and foibles.

Shows that select and feature CC music - like The Bugcast (disclosure: my own show) - filter out a lot of the chaff, and probably insert some too!

Cheers,
