Hello,
I've seen you dicussing about licensing music.
So I want to raise a new topic. Are there musicians on this list? How about making music to advertise free software? There are already a few examples, but only few.
If you need inspiration have a look there: http://gnu.mirror.xaranet.de/fun/humor.html#Music
Well, the songs of the OpenBSD project do not always reflect the opinions of the FSF, the latest is even oposed to the FSF. But still I think they are good examples for free software advertising songs: http://openbsd.informatik.uni-erlangen.de/lyrics.html
Of course songs for free software should also be freely available. The song "Follow the GNU" by Void Main would be a good example, if it only was freely available. The band wanted to make it free, but they were bound by their contract.
That's another big obstacle. As far as I know, musicians who have a contract with the GEMA cannot make free music anymore. I think a contract with the GEMA eeven covers songs written before the signing.
