i'd agree that this may be different.
there are more corporate hands in the stew and it makes
a lot of finished products less daring.

but let's take a step back.
most of your favorite classic albums that were super innovative didnt sell that well.
especially if you look at rap.

a lot of classics got to be classics because rap wasnt fully commodified yet.
artists essentially did what they wanted because corporate hands were not paying attention to the artists.

that's not different from what happened to punk/ rock/ *insert older genre*

the system has not changed.
our awareness of that system may have changed,
but the amount of good music has not changed.

most of it is, and has always been, crap.
