Cool bit of audio mixing. I'd appreciate "IMissLiveSports" personally, and "IMissLiveMusic" that could played in the background of any other music would be fun, too.
The NFL was piping crowd noise in to their empty stadiums all season. Some games seemed to have a live person controlling the crowd reactions. Not the same, but I got used to it. For the music, can't you just listen to recordings from live concerts? Those usually have plenty of crowd noise.
