Smoking gave you dopamine
Music gives you dopamine
I played guitar at a friends house 10 hours a day the first two weeks of my quit.
Playing an instrument has your brain firing on all cylinders. Listening to music affects emotions which also stimulates dopamine release.
"The emotional climax of a song was not actually the part responsible for musical frisson; it seems the of emotional release during the tension-building moments matters just as much as the eventual resolution in giving us that tingling feeling."
(This works the same way with food. Thinking about food you want to have releases dopamine BEFORE YOU ACTUALLY EAT THE FOOD)
