Posted this elsewhere earlier and thought since the image is so awesome and the post became so long, it was worthy of a dev lab update.
So, what I'm thinking of doing is potentially including great indie music artists tracks in-game (with permission first of course). The mock-up image below shows how the music player (called the ES Ra(u)dio Player, pronounced Raw-d-o) dialog will probably look and shows the ability for the user to find out more information about an artist / track as well buy content from them (Your album cover doesn't need to be as dope as Big Dog Mendoza's).

Basically (to begin with at least) aDance gets free cool music streamed in-game that matches the style / arena theme and musicians get extra listeners / fans for their music, a bit like EA Trax but indie with included artists getting direct links and an opportunity to sell their content to potentially millions of players (that's what a top end flash game gets, I'm aiming at that floor). All content will be served via XML meaning easy live updates of songs, descriptions and links. Artists will have the ability to see how many players do what with your content (ie click the buy button or add to their favourites etc).
This is all brainstorming at the moment and an idea based on the fact that I do exactly the same thing with arena content (xml based data) currently.
Right, that's all, I need to actual get back to game development for some new content to share, back to the carnage I suppose.
