What instrumental song, when listening to it, causes your mind to try to fill it with lyrics the most?

Little Martha by The Allman Brothers does the weirdest thing in my brain. It’s just a fantastic instrumental acoustic guitar piece, but my brain desperately tries to “find” words in the melody. It’s almost like it’s a foreign language and I’m trying to suss out the meaning somehow. I’ve never run into another song that does that.

interstellar overdrive from pink floyd

the swirl of sound is a special language of its own

It's kind of cheating, but [Popplagið] by Sigur Rós. I'd argue that the vocals in it are instrumental, since they're in a made-up language consisting of gibberish words.

Because I am doing a playthrough Morrowind main theme.

I always imagined lyrics for Super Mario Land world 3 when playing as a kid.

🎶Nimm mich mit, nach Little America.🎶

I don't remember anything else.

Batman. I like to add "duh nuh nuh nuh" and "BATMAN!"
