Dissect it into: IF (you have some jazz) or (you have some blues).
Determine the truth values of the two clauses.
If neither of them is true, the if evaluates to false. If either one of them is true, or both are true, the if evaluates to true.
Comparing to the AND example... Grammatically, perhaps there should be no difference from "you can X or Y" amd "If you can X or Y" other than adding an IF, but semantically, the former usually means something AND-like and the latter usually means something OR-like. You have to know what X and Y actually mean to determine what logic makes the most sense. Grammar along certainly won't tell you.
