WHAT IS THE MOST UNIQUE SONG THAT YOU HAVE EVER HEARD?

Song title Horizontal Hold by This Heat. The Made Available John Peele is the best. Some creative individual made an unofficial music video that syncs VERY well, https://youtu.be/yGILNOnVWK8

Second choice is a song titled Super Are from the Boredoms.

It's probably a minority of people who would refer to either track as music; more like an assault. I’m a weirdo.

Alice’s Restaurant  by Arlo Guthrie

Anything by the Last Poets

Train Time by Cream

Album Lee Michaels, lot of music for two guys

As has been previously mentioned, They're Coming To Take Me Away by Napoleon XIV. I was just a child when this came out, I recall the total strangeness being both intriguing and scary. This song was  totally in my mind when as a child I and best friend rode our bikes perhaps 20 miles one way onto the grounds of a state forensic psychiatric hospital. Very strange and scary experience.

For entire album, Clear Light's Clear Light, one pretty crazy psychedelic album from an era of crazy psychedelia. West Coast Pop Art Experimental Band also has some pretty crazy tracks. They also have an unusual story in that they were largely financed by an older wealthy abusive wanna be hippie who insisted on being part of the band.

I don't know if it is the most unique, but, I nominate Hasil Adkins' "We Got a Date."  This is a self-recorded rockabillly/punk song that came out before mainstream punk became popular.
