8. "Who's Got the Herb?" - Human Rights (HR)

Speaking of punk rock... Singer HR's roots-reggae side projects still have the edge he had with his other, more hardcore band, Bad Brains. This song has since been butchered covered by 311 - but don't let that stop you from enjoying the original.

Barrington Levy wrote a lot of songs referencing ganja, and he's still around singing them to this day. Literally. Mr. Levy is performing this week at City Hall along with Giant Panda Guerrilla Dub Squad.
