"Melodies of Life" is a lovely song, indeed; I haven't played any Final Fantasy
games but I've always adored the song, both in English and Japanese. After watching these type of videos on YouTube, I too wish to play the piano. Or if it weren't YouTube, it'd be one of my close real life friends. She's been taking piano lessons since she was very young, and once she played "Eternal Snow" from the anime Full Moon wo Sagashite
and I cried. It was embarrassing, in front of her family and some of my other friends.
Here are two piano videos I favorited on my YouTube account:
YouTube - Caramelldansen - Piano [MP3 Available]
(Caramelldansen - it surprisingly sounds very nice, and not obnoxious like the actual song)
YouTube - ピアノで「Ark（Sound Horizon）」
("Ark" by Sound Horizon)
I don't know how to post media... eheh.
