show tunes 

The style of music in musicals. They can range from really freakin' annoying to wonderfully witty. They are used to convey an emotion in the character, continue the story of the play, create irony, or jsut about anything the writer wants.

The most un-PC show tune ever was "Springtime for Hitler".
