Some bands I generally love, or like a lot, and my choice for their worst songs:
Blur: "Alex's Song"
Pink Floyd: "Not Now John"
Arctic Monkeys: "The Bad Thing"
Duran Duran: "Hothead"
Meat Puppets: "Bad Love"
Green Day: "Are We the Waiting"
The Kinks: "Maximum Consumption"
R.E.M.: "The Sidewinder Sleeps Tonite"
Fall Out Boy: "Sending Postcards From A Plane Crash [Wish You Were Her]"
Funny, I played this for the first time one or two days ago, if you look in an earier page i nominated TFMH, hoping the rest of The Final Cut wasn't like it, but i really found it hard to click with this one specifically, its too random, messy, and the female vocals make it cheesy.
Sidewinder isn't that bad of a song. I'm surprised there isn't enough hate in the world for A_A_A_A (which i like) but first time i heard it, i thought it would be the Crazy Beat of CIN. Maybe its too recent
Blur - Sunnyside Farm, Country House *though reasonably OK for nostalgic reasons*
Red Hot Chili Peppers - Mommy, Where's Daddy?
The Clash - Career Opportunities (Sandinisita! version) (children, really?)
Wolfstone - Tracks from the disowned albums Wolfstone and Wolfstone II, though i like Reconstruction
