The crack team of Dave Soldier and Komar & Melamid have scientifically created the world’s worst song:
It clocks in at over 20 minutes. The trio has a Web site where they asked visitors to list their most hated sounds, be they operatic hip-hop with cowboy lyrics, swelling harps or marching-band music from hell. They claim that “fewer than 200 individuals of the world’s total population will enjoy this,” but released it anyhow.
I listened to it. (Okay, I listened to ten minutes. I dare you to go longer.) It’s not the skin-twitching irritation I thought it would be, but it is very strange, tin-eared elevator music–the kind of thing you would not want to listen to after leaving a party chemically altered. Who knows where you’d end up…

I haven't listened to the whole thing (heard some of it on NPR) but you should look up their work with best & worst paintings – starring George Washington and deer that can walk on water. http://www.komarandmelamid.org/chronology/1994_1997_peoples/index.htmAlso, I met them 25 years ago at an event where they bought my soul for $5.00. I expect to see it on Ebay any day now.Riva
Scientifically create, sure. Whereas to engineer the worst song, all you have to do is run a 70s pop tune through MS Songsmith. Which by now, given the recurring meme I’ve seen on youtube, has already been done to death.Go Microsoft.
