It used to be on my music playlist on Youtube from a few years ago but mysteriously vanished and I can't find it. I think it might've been an unfinished song, or at least was short, no more than 2 minutes long.

The song sounds very very similar to the start of Glass Animals - Gooey https://www.youtube.com/watch?v=jeo3an2M_Lo both in the tune and in what the instrumental sounded like, but it's not the song and it's probably not the same artist. I'm bad at identifying what genre a song is so it's probably whatever genre Glass Animals - Gooey is.

I whistled the tune and beat here: https://vocaroo.com/124IOs8jrfwz

That tune above is basically repeated through the whole song, just with a few more elements added to it later, and it has feminine vocals that sound like they're saying "goody... goody... goody... I do". I don't think they're meant to be clear words, though, and so it probably wouldn't show up as lyrics on a lyrics website, and tbh it might be subjective what the vocals sound like they're saying anyway.

I want to add it to my music playlist again but I can't find it and I don't remember the title or artist :(
