Ai no Tame ni.
Overview. "Ai no Tame ni." was written, composed and produced by Tetsurō Oda, marking their first collaboration. The song served as theme song for the TV Asahi drama "Ace o Nerae!", starring Ueto herself. Unlike her previous singles, which were all based on a darker, edgier concept, "Ai no Tame ni." is Ueto' first light-hearted, cheerful single. CDJournal described the song as a "fresh, juvenescent ska-pop track," while Barks complemented Oda for composing a song that fit the modern take of the drama on the original "Ace o Nerae!" manga perfectly. The B-side , "Arigato," was also produced by Oda, and written by Oda protégé Akira Nakazawa. The single also includes a 1980s-inspired remix of "Binetsu." Chart performance. "Ai no Tame ni." debuted on the Oricon Daily Singles chart at number 7 on February 3, 2004 and climbed to number 4 on February 7, 2004. It peaked at number 6 on the Oricon Weekly Singles chart, with 31,006 copies sold in its first week. The single charted for fifteen weeks and has sold a total of 99,470 copies.
