I always struggle with these kinds of questions - either I'm amazingly eclectic in tastes, amazingly changeable or amazingly undecisive... Can't quite make up my mind!
Now, if I really must... I'd say recently I've been listening to Scissor Sisters a lot, not to mention the re-discovery of 80s bands like Blow Monkeys and Curiosity Killed the Cat - did anybody like these?
Some of my all-time faves tho are U2, Red Hot Chilli Pepper, INXS, The Cure, and Jamiroquai... Not much of a straight answer, I know....
