They have a reputation about being just another "boy band" which is far from the truth. On top of the evidence provided below they also write their own songs, play their own instruments, sing live and have their own record label. They have a couple of lame ballads, yes, but a bunch of their songs are actually great. Like Shine A Light and Too Close For Comfort. Another thing is that these guys is a very good live band - they sing and play extremely well.
SO! Prepare to have your preconceived notions torn apart.
