They were nominated for Best New Artist this year. If you ask me they aren't a new artist. They have been being pushed by Disney for at least 3 years and I definitely wouldn't say their THIRD album by any definition can be called their first album that established their identity. There is nothing about their identity that has changed since Disney established it for them when they were new artists 2-4 years ago.
I could go on a long rant about how much and why I hate them, but I am just going to leave it at a simple kudos to Adele. She won best new artist and the Jonas Brothers did not! I was cheering for her and Duffy, bust mostly I was cheering for anyone but the Jonas Brothers.
In case you were wondering Adele signed with a record label at the end of 2007 and released her first album in 2008, a true new artist in 2008.
