We promise not to put the winning song in a time capsule for future generations.
Our criteria for the nominees: the song can't just be bad, because bad songs can be mighty entertaining. It should have received a lot of radio airplay in its day, and it must have no redeeming value whatsoever. Bad, hackneyed melodies, insipid or dopey lyrics, overblown production or horrifying keyboard solos are all assets here. Novelty songs don't count, as they constitute a different, distinct brand of putridness.
A helpful hint for people casting votes: If simply reading a song title elicits a retching sound or a spasmodic clutching of the gut, then search no more. This is the tune to vote for. Vote for as many songs in each category as you want. We're breaking it up into a series of several contests, one for each wretched time period, to drag this out as long as possible.
