Ahhh, but everyone who doesn't like heavy metal/hard rock has something wrong with them.. or at least that's what they tell us!
At times I think people forget that the music on game nights needs to appeal to as many people as possible - not just their own personal taste. I would agree that rock is more likely to get the players adrenalin pumping more than pop or dance - but if I haven't heard of most of the bands on this thread then I would guess I'm not alone.
So yeh - more Saturdays, more S Club 7, a bit of Chipmunk, Tinchy Strider, NDubz and of course the obligatory Black Eyed Peas.
Please.
