Trying to find + download a song that doesn't exist anymore?

Hi! This might sound a bit random, but I recently remembered a song that means a lot to me — Rely on by Akon — and I’d really love to add it to my playlist. Unfortunately, I can’t seem to find it anywhere anymore (it’s not on Apple Music, YouTube, or other platforms).

The only place I’ve been able to find it is here: https://share.google/gcyqyKatZifpK8pcn

I was just wondering if there’s any way I could download it onto my phone?
