The title track, "Grateful Days", samples the opening of "Today" by The Smashing Pumpkins and features fellow Japanese hip hop artist Zeebra and "The Queen of Japanese Lady Soul" Aco. The song quickly became a huge hit in Japan, reaching No. 1 on the Oricon charts, and remains a favorite among Dragon Ash fans.

The track also samples Pachelbel's Canon in the style of Coolio's "C U when U get there" and a live version of this track actually changes the chorus to the chorus of said track.^[1]
