One of the things that is bittersweet about learning a song is that it can take the magic out of the song; instead of just hearing it, I am thinking in chord shapes, positions, lead lines, etc.

I can't even Phish because if I'm on drugs I fall into listening-like-I-need-to-play-the-next-chord. Whereas a lot of songwriter music I can listen-like-I'm-reading-underegrad-poetry

I do feel that way about tetris, too. I think the reason I enjoy older jazz standards on bass is playing them is a little like solving a suduko- I can get a satisfying answer without much more than the melody. That doesn't work for modern rock where the riff is key. That kind of "well, it sounds okay but it doesn't line up with my idea of what makes sense" is my own anti-magical-feeling.
