This song was so interesting to listen to and the both the lyrics and video beautiful. For any English speakers in the comments, the song translates to "Art I don't know" and is about getting so caught up in the details of life and the stories you read and experience that before you know it, you don't know about the art that's being sold anymore. Or that's what I get from an inaccurate translation with some Japanese knowledge. Might look at doing a properly proofread translation if it stays in my playlists.
