This applies to the musical composition of a song. Ruki is the primary lyricist, but frequently the individual members will compose the music to fit his lyrics (or he will write lyrics to fit their songs). If a song has been credited to a specific band-member as the primary composer of the music (credited in the booklet or in an interview, etc.), I have tried to include a tag for it. All other untagged songs are either composed by the band as a group or simply uncredited to any specific band-member.
