Justin Bieber has definitely got the vote for me. Although One Direction are pretty close behind him. He sings these generic songs about love, although he has yet to actually experience anything past having a girlfriend which means nothing in this day and age. All his songs do is to basically allow any girl, or boy, to place themselves into the song and feel like he is actually speaking to them. It requires no skill to do, he doesn't even write most of his own songs anyway and yet here we are, he is one of the most famous singers in the world.
One Direction gets a mention on this list because recently they broke a record of being the first British artist/group to actually have a début album début at number 1 in the USA or something along those lines. If we had the technology we do today in the 60's then the Beatles would have probably done that one with extreme ease, and many more bands after them. I think that people take that record as meaning something much more than it actually does.
