Not sure what they're doing this season as I've only been to one game, but a season or two ago the supporters panel asked people to nominate tunes - they put together a playlist, which was then played again and again in exactly the same order, every match for the following season or more.
At the back end of last season they did a good thing where they got people to nominate songs by female artists for before the game when they were doing the Her Game Too match - they had the volume down too far for half of pre-match, but eventually when they turned it up, it was banging.
I suggested somebody should put together a special playlist for every home match, and indeed offered to do it if nobody else was able to, but my idea and offer were roundly ignored.
