3. Mary Jane - Rick James (1978)
I'm in love with Mary Jane/ She's my main thing.
This R&B ode to James' favorite lady, the smokeable kind, plays with double entendres. It appears on his debut, Come Get It!, and climbed to No. 41 on the charts. The song has been widely sampled and Coolio adapted it for "(I'm in Love with) Mary Jane" on the Half Baked soundtrack (1998).
