I'm going to reach back to an earlier generation of songs for more awfulness. Any of the 1950's "teen angel"-type songs where somebody dies qualify as sappy and bad. The 60's version of this particular variety of song would have been Bobby Goldsboro's "Honey". Then there were a couple of them in the 70's - the Heywoods' "Billy Don't Be a Hero", and one by some one-hit-wonder whose name escapes me called "Run Joey Run". Seems that "Joey" has knocked up his girlfriend, who is now begging "Daddy" not to shoot him. Daddy's a bad shot and hits her, instead. The girl singing the part of the dying poor young thing sounds about 10 .... making this one of the creepiest songs ever, as well as the worst.
