For feature requests, I'd love to be able just to watch them being played automagically one after the other on my iOS device (on the website or app), or computer via the website.

Sometimes I just want to lay there with headphones on and listens to good piano music.

Really enjoyed playing with this, actually still enjoying :)

This is awesome! The tutorial is a good touch!

You might also want to add direct links to songs for easier sharing for specific pieces, as well as putting the song name in the auto-hiding bottom bar because my memory isn't what it used to be.

Hungarian Rhapsody #2 is the first thing I went looking for. :)

BTW, one simple feature that would make this much more interesting to me would be the ability to skip back 30 seconds and try a section of a song again. Just a suggestion.
