Initially, the idea was to make 18 songs to celebrate the 25th Anniversary, starting with one selected from those 18. However, later we understood, that it was too much work and almost impossible for us to finish. So, only that one chosen songs was recorded.
The initial principle was the following: we chose one song from each studio album, from each EP, both Feedback Files, from songs sang by Kensuke Kita, from indie period, from those which weren't present in the previous categories, and Yellow as Takahiro Yamada's song.
The results of the first questionnaire are present here:
As a second step, all of those winning songs went to a second tour to chose one song to cover first. It was a triple tie...
Then, we had to chose between those three. In that last but not least survey Solanin won.
