Here's a graph that plots average SAT score vs music types / bands.
Pretty fascinating. Guster, Ben Folds, Sufjan Stevens and Counting
Crows are at the top range. Not surprising at all. Note Lil Wayne at
the far left. Kanye West / Outkast always did strike me as
significantly more intelligent / cerebral than average rap, too.
Surprises: How did Jazz end up so low?
