Query: Songs sound like they were each written in about 20 minutes...

..this is what happens when hipster fashionista lead singer moves to Hollywood and the band has to fly there to meet her and write songs. Just goes to show that "Maps" was an anomolie, and that this band is exactly what most of it's haters have said all along: all style, very little substance. It's hard to be anything other than that with someone like Karen O as frontperson.
