This is the beginning of the Free Music Push. (Libre Free that is. FAIF Free that is.)
I tend to agree, though it's hard. Much easier with software, because there's functional equivalence. I can use OpenOffice.org instead of Microsoft Office, but I wouldn't really listen to Brad Sucks instead of Tool, it's not a replacement.But still, I agree. We should support and seek out freely licensed music, even though it's hard for it to function as a replacement for other music we might know and love.
