One of my secret, until now, vices, is listening to Aqua[^]. For a bloke who listens to Bruckner, Mahler, Philip Glass etc that might seem quite a jump. But I can't help it; I just like listening to their disco mixes.
I think it's because they sound so happy. No angst there.
I will confess though that I always check to see who's around when I select their music. I have a mystique to maintain and who knows how it might crumble if it got around that I listen to Aqua!
