Real Emotion was the opening song to the video game, Final Fantasy X-2. Whatever you thought of that game, and I quite liked it, the song and accompanying video certainly set the tone. The original song was performed by Koda Kumi in the original Japanese, and Jade Villalon of German band Sweetbox in the English edition.
I don’t know what put me in the mood to listen to it, but I did find this cool cover by Nylon Pink:
It does put a different spin on the song.
If you’d care to hear the original English version from the game, I’ll chuck that into the post as well. It looks great with the HD remake:
Almost makes me want to play it!
