Thoughts on a Concept Idea

 I was thinking of submitting a concept where a game references a song or song title, like how Rock Band 1 & Guitar Hero 3 have venue that reference Iron Maiden's 22 Acacia Avenue. Good idea or too narrow? Should there also be one for movies, TV as well or should they all be combined into one? Any ideas on names for the concepts as well?

That but could also be a name of a level or article of clothing or weapon, etc that references a song as well.

sounds like a good idea, but what would you call it? maybe "Music reference" "song reference"
