When I was younger I used to get lost playing the piano (still do actually). At the weekend I would sometimes get up, have breakfast, and then play through the whole of the day without even realising, thinking it had only been a couple of hours.
Love Zelda music in orchestral form:
Ahh, calm days like those can't be described in words.
