2010's Most Disappointing Album

I forgot to post this last month, but the most disappointing album I heard in 2010 was Kings of Leon's Come Around Sundown. This is a band I really like, have since their first album in 2003, but this was a thud of a release. One of those dreaded "how do we follow our big breakthrough?" types of albums. Lacking many of the hooks of 2008's Only By The Night, what I heard was a band that was tired and just going through the motions. What a letdown. But like I said, they are still a band that I like, but this time they struck out.
