A guy named Darryl W. Bullock blogs about the world's worst records. Like Bullock, I have an appreciation for truly awful records. But he blogs specifically about the topic. As near as I can figure, he sticks to a once-per -week schedule, and typically includes audio, so you can hear the awful songs.
Interesting for me, he discusses a lot of music that I have in my collection, though I typically have them on compilations as opposed to having the original single. That's true of Eilert Pilarm, a Swedish Elvis impersonator who doesn't have a good enough grasp of English to pull it off. Also of Congresswoman Malinda Jackson Parker (yes, she was a congresswoman -- in Liberia) who recorded two songs about mosquities. Here is one of them:
I also enjoyed Bullock's entry on The Buggs (a thinly disguised Beatles ripoff from the 1960s), largely because he discussed a truly awful record that I used to own on vinyl.
I love perusing Bullock's blog, and repeatedly finding myself saying, "Yeah! I remember that! I remember that!" Go give it a read.
