My Chemical Romance - Danger Days (album).
I loved their first 2 albums, but this new one... meh. It doesn't even sound like them. I've been trying to put my finger on what exactly is different, and all I've come up with is "pop"y guitar work, and all the songs seeming to just blend into each other. There's no real hook between individual songs... the album has a hook, sure, (one I don't particularly care for) but the songs all sound too similar to me.
Either the whole band had a sudden change of heart over what style of music they wanted to make, or they just lost their muse at a critical time.
NOTE: All the above is simply my opinion. I'm hoping this new album grows on me, because I've loved My Chemical Romance for a long time. Now I think I'll have to post a link to their song Helena off the Three Cheers For Sweet Revenge album to remind myself why I became a fan of theirs in the first place...

Warning: Gothic/Emo imagery. (Which is why I love it.
That and it's a great song, IMO.)
