Worst album title of 2004 (non-hiphop division):
"Honkin' On Bobo" by Aerosmith
I am aware that the CD cover features a harmonica. I don't care if this explicates the title, in that "Bobo" is the name of an instrument and Bobo has been honked upon in the making of this record. It's still an awful name.
I am also aware that Aerosmith ceases to be musically relevant, but that doesn't prevent them from claiming the award.
