Spin magazine weighed in with their 15 Worst Album Titles of The Year list, and most of it's pretty on point. I can't get behind an album called "Raditude" (Weezer) or "Loudest Common Denominator" (Drowning Pool).
None of this years list is as bad as the worst album title of all time, which is of course Guns N' Roses' "The Spaghetti Incident". It is only August, though.
Update: Sometime LNMC contributor Spencer Kent sent me this list of the worst album titles of all time from Cracked.
