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

Can't say one but there are a few very special songs that touch my heart. Among them are

Like a rolling stone, Just like a Woman  of Bob Dylan
Quite a few Jimi Hendrix's songs among them Crosstown Traffic, Red House, Little Wing, Castles made of sand, bold as love
Wild horses      Rolling Stones

Let it be  Beatles
Give it up to love   Mighty Sam Mcclain
And there more ...

That would be “Horsey Horsey”, by Buzzard Bait.

Captain Beefheart needs to be on this list, I'll go with ;Old Fart at Play; from Trout Mask:

I'd add:

Nights in White Satin, Moody Blues?  (Didn't see it, but this thread is three pp. long)

Black Diamond Bay,  Bob Dylan

Man on the Moon; E Bow the Letter, REM

+1 to those mentioning Captain Beefheart, specifically Trout Mask Replica.

The Blimp is another great one from that album:
