Annie Mac , BBC Radio 1 now (UK). She does a "Battle Rhythms" section in the last 20 mins of her show. Tracks played by both artists, and people text in to say who they like most. I guess it's turning music into a competition. But hey you know it has to be the Brothers.
By the way in Ireland (where I originally come from) to go to the Jacks means the toilets. Is this where Basement Jaxx got their name from?...

This is really not a fair competition is it? Basement Jaxx just aren't in the same league!
