"Riddin Dirty" by Paul Wall was my burning on the way to the spot jam for the longest time. Reminds me of old Cronic jams from Dre and Snoop back in the day.
Also, the screwed version of Paul Wall and Chamillionaires "Get Your Mind Correct" has lots of good stoney jams on it.
"Welcome To Jamrock" Damien Marley
I also went through a long phase of kind bud, then jamming The Mars Volta's "Frances the Mute" with a scotch. Got to really want to chill for that one though, last song is like 30 minutes long.
And if I actually wanted to smoke a blunt, which I never do, but if I did, I would probably roll with Mobb Deep "Infamous".
