I think James is very very good, though very depressing. Even when he smiles he looks sad and depressed.
Is there any more space for yet another boyband...maybe. If One Direction (who IMO are terrible) have made it big, why couldnt another boyband?
I'm pretty damn sure the XF producers have told him to milk the angst-spiel for all it is worth at all time... his mother has publically admitted that his "my family is completely broken and I had to seep rough" story was very exaggerrated. Don't get me wrong, I understand why he does it, he has the chance to change his life and make a fortune, but I wouldn't take it as gospel.
If you listen to the songs on his bands website then you will see a completely different side... the music is upbeat and he sings that way too, and sounds rlatively cheery during the comments he makes on the tracks http://www.jamesarthurband.com/
I bought the album the other day (it's only 6EUR) and really like it, and i'll continue to buy his stuff in future providing he doesn't do anything daft with his music.
