Musicians

and artists who use the music to make a point?

I was speaking historically.

Personally I believe music as well as other art forms are there to speak to the times on many occasions. It is up to the individual to reject or use the information the art is presenting or even how it is interpreted.

I was also speaking mainly of music without the poetry or lyrics. Sorry. I would hate to lose so much of the classical repertoire by rejecting the music because of the politics behind it.
