Well...in the ideas defense. You could say this is already a social networking site in the making because of the Armatars, About, Messenger, and Forums. So you could say music is not going to make it any more social than it is.
Plus, Music is not social, it is just for fun and so you can listen to music without opening a new window.
But i am still against it. It would be very difficult to code something like that, and where does the song come from? AG would have to create a music section, and then get all the artists there. The only option i see, as far-fetched as it is is making the About HTML compatible so we can stick in Project Playlist playlists.
