Lion Heart – SMAP

SMAP is a five-member idol group so popular they’re often called a national sensation, and they expanded their reach not only as a group but also as individual performers.

Their 32nd single, “Lion Heart,” used as the theme song for the TV drama Food Fight, became a huge hit, helped by the popularity of its B-side, “Orange.” Since it’s a male vocal song, it may be difficult for women to sing in the original key, but even for men the overall key is low, so singing it an octave higher will sound nice.
