Finally, the single came today early.
I am listening the whole single, 僕らはまだ the melody has a feeling of sad tune. It sounded the group's farewell. I am sad listening the melody especially the instrumental version.
95 groove is my favourite song in the single. This is my own analogy why it is 95 groove? 1995 is the year they established as a group, and they are still grooving until now. ;)
Maybe that is the story behind the title?
