Musical boner 

When music is so good it becomes arousing.

Dude, i had a musical boner all the way through the tame impala concert last night.

Musical Boner 

When someone sings so well, so much dopamine is released and spread, that it gives either the singer or the audience a boner.

Person one: Dude! did you hear Alice Cooper's Poison on the radio yesterday?
Person two: Hell yeah! I swear I got a Musical boner about halfway through!

The way a pretty girl might give a man an erection, a culinary boner is music that excites people.

Dude 1: Have you heard the new Radiohead?

Dude 2: Yeah, and I had a huge musical boner. It's awesome!
