本当の音 (Hontou no Oto)
For a long,
long time my all time favorite Japanese song was Mai Kuraki's Secret of My Heart, for reasons that are too boring to disclose here. But I was looking for new music to listen to on youtube, typed in something like 'Beautiful Japanese Music' and that popped up and oh my gaaawd, Secret of My Heart fell down to second place immediately.
Came to AHS found her discography (Thank God for Tomoyo xD) and downloaded pretty much everything right there and then. Battle of Destiny is a close second, though. Follow the Nightingale. I believe~海の底から~. EXEC_COSMOFLIPS (anyone have any idea why that song is called that? Cause I haven't a clue.) 大人のオオカミ (Otona no Ookami)...
...you asked for one song and I totally just gave you a mini-album's worth.
本当の音 (Hontou no Oto)
That's it. That was the song. The end.
