I'm currently watching the TV show "Breaking Bad" and I dont understand what seems to be slang.
Context: some characters (who are drug users) are listening to music on a brand new sound system. They are enjoying it, especially the light effects. One of the character stands that he could watch it all day, and another answers
"Totally makes me wanna crank old Sabbath and blaze one".
I understand that "blaze one" means smoking marijuana, but I dont understand the beginning. To me it could either be a reference to Black Sabbath (metal music band) but they are listening to rap-music, or it could be a jewish reference but I dont think any hint indicates that the talking character is Jewish (I may have missed the reference though).
The episode I refer to is 4.2, "Snub 38" (timemark around 7:50) if it helps.
