Jun Senoue on The Best of Crush 40: Super Sonic Songs:
Sonic Heroes
This is what we handled thinking of making an easy-to-understand and catchy song that resembles a theme song of an anime show. No matter which one—the demo inserted into the instrumental melody made in the beginning or the recorded tentative song by myself—I let the development team listen to, they were lacking reactions, but when Johnny sang along with almost the same melody in addition to the same piece in gibberish, oh wow weird, it was very well-received in no time!? It’s a song that shows us the importance of the voice, namely the vocal on the occasion of letting a third person listen to it for the first time, or rather the power that the voice carries. I had not thought it was such popular song, so in the live performance of Tokyo Game Show 2008, I was surprised that the reactions towards this song were big beyond imagination.
