Stoner Decor

How is it that stoners have been listening exclusively to the same 5 bands since 1968? Have there been no major improvements in stoner music in the last 40 years? I'd bet my third nipple that the framed record hanging on the wall next to the pot leaf poster is Bob Marley, the Grateful Dead, Phish, or Dave Matthews.

Hey, if it ain't broke, don't fix it, right?
