This doesn't make sense to me. I mean, the term "remix" literally comes from the music scene.

Artists are constantly getting inspiration from one another, referencing one another, performing together or having their works exhibited together...

While there are some big name artists who are famously protective of the concept of IP, those artists have made headlines exactly because when they litigate they seem so unreasonable compared to the bedroom musicians and pub bands and church choirs and school teachers and wedding DJs and millions of other artists and performers whose way of participating in "the culture" is much less tied to ownership.
