There are of course good musicians who distribute their music monetarily free but how much of it is explicitly copyright free (i.e libre not gratis)?
I know a number of aspiring musicians who if a large media company took their music and redistributed it under a different name with different people lip syncing to their vocals then boy would they be pissed.
