Google Play app link says "We're sorry, the requested URL was not found on this server." Surprisingly satisfying -- I think my heart rate dropped a good 10 bpm in a few minutes of playing. I'd love a little map to know how far I am in the song, and some way to work pedals for dynamics for more advanced users; I don't play piano, but I'm a musician and am familiar enough with many of these pieces to have opinions on the expression. If I could map it to custom keys that would be perfect -- I happen to have flight pedals. Obviously that's atypical.
