> Billions of listens vs. thousands (?) of shirts.

how much of the revenue derived from those listens turn into commission to the musicians?

Those t-shirt sales came about because of those listens, so even tho the music wasn't as revenue generating, it acts as the biggest funnel.

I mean I sort of believe that most Ramones t-shirt sales came along because of the listens, but then again I see lots of Misfits t-shirts on kids born this century and considering it's in Denmark it seems unlikely it's because their parents were big Misfits fans.

Of course Misfits had a much more impressive visual aesthetic, so that might explain their continuing design relevance.
