“…’till now, you have used free software, and now you can
listen(and even participate!) to free music too…”
Yanez, croatian HC band, started to distribute their songs under
license similar to GPL (you can download their music for free on
their homepage and even participate in process of
making their music). More interesting is that they released a
song about Linux which you can download from
their homepage in MP3
format.
