Crystal Kay - LOST CHILD...simply perfect, beautiful, soothing, ethereal, dreamy...I really would love to know who composed it

[even though, honestly, it ties with ayu's BLUE BIRD, Do As infinity's 魔法の言葉 ~Would you marry me? (Mahou no Kotoba ~Would you marry me?~), Koda Kumi's 恋のつぼみ (Koi No Tsubomi), ELT's ソラアイ (SORAAI), BONNIE PINK's Answer~ひとつになる時~, hitomi's IS IT YOU? / Wish / 君のとなり (kimi no tonari), and Mika Nakashima's RESISTANCE / 朧月夜~祈り (Oborodzukiyo ~Inori) / 火の鳥 (Hi no Tori)]
