I think it's deliberately dissonant in comparison to the regular running of the ship.I don't feel were supposed to like or dislike it. Severin and his group liked it, a lot of the crew liked it. Scotty, that crabby old bastard, didn't. I thought it was fine, but really liked the jam session with Spock.
Liking music, of course, is a subjective thing. I don't care about it one way or the other since it served the story fine.
