Westlife, Classic.

Westlife has never cease to amaze me, I really don't have the slightest clue. Anyways, you just can't beat the classic. I've grown up listening to them and even though there are so many amazing bands out there ( cough, cough, All Time Low, wink, wink) Westlife is still pretty awesome, they're simply irreplaceable as they are unforgettable. Haha, did that just make sense, I hope it did.
