Ayumi Hamasaki to contribute two songs to a VG

[Tasked]

そして、なんと浜崎あゆみとの豪華タイアップが実現！
浜崎あゆみ書きおろしの新曲 「Startin‘」 がオープニングテーマ、「rainy day」 がエンディングソングとして流れ、『新 鬼武者』の世界を華やかに彩ります！！

It states that Ayu has two new songs (I think on the album, but it doesn't specificly say that) that are used in a PS2 game called "新 鬼武者 DAWN OF DREAMS":
"Startin'" = opening theme
"rainy day" = ending theme
The game is supposively a very good and popular capcom-game. the picture at the top of this post shows that appearantly there's a video with a (preview) of the song 'startin'' somewhere already.
