Man, that sucks. To be honest, I can't believe my ears still work either. I was a little bit of a party person in my teens/twenties. My mates owned a fat rig, so most weekends were spent in the woods, dancing. Then I discovered snowboarding, so headphones glued to my ears for about ten years 😳 🙃

So. I bought the track, downloaded it and used Transcribe to try and isolate what was happening. I *think* that the 2-2:22 section *might* be some quiet vocalisation of the melody being played.
