That's what I got. But when I did it the first time, I got a tune. I tried it again & on the 2nd tap which I tapped harder & he sighed, I got another tune. 3 tunes so far.
I came across it by accident. For the 3 tap's, I tapped 1 normal, 2nd hard & the 3rd normal.
Not a tune for each tap but a different tune per session.
Just blew my mind away. According to what I read, there is a tune but not 3. Must play around with it more & try to place the tunes I get.
