A面/B面
Wanting to contrast something unusual with a pop background, hide hired Yukinojo Mori to pen the lyrics to his first two A-sides. As a kid, hide was fond of Bow Wow's 1982 album "Warning from Stardust", where the A-side songs had lyrics in English and the B-side in Japanese. Liking the Japanese lyrics better, hide only realized Mori was their author afterwards. "50% &amp; 50%" was written after the A-side and B-side on "Eyes Love You"
