Looking for a very odd song

Years and years ago there used to be a song with a very, very poorly animated video with it(shocker, I know). It starts off with Len saying he wants to make a song, Rin offers to join him after a little back and forth and eventually they duet.

I believe it was called “I’ll make music” or something along those lines. Not to be mistaken with “I’ll quit making music”

It’s nowhere on Spotify and I can’t find it on YouTube anymore after digging for it obsessively. Just wanted to see if anyone else knows what I’m on about and maybe a link to be shared…
