The singer (Luka) talks about how they continue spinning around endlessly without stopping.
Despite the fact that the singer's friends are farther reaching and better at spinning, she persists in trying to increase their reach, starting from 85 cm to 250 cm and then reaching 5200 cm, at which point the singer starts flying.
Finally, with a reach of 6300 km in radius and tilted at 23.4 degrees, the singer looks down and sees a colorful scene that they didn't notice before.
Then Luka finally asks to be accompanied if they someday tire of spinning.

"Anata ni Hana o Watashi ni Uta o" is an original Hatsune Miku song. It is one of Re:nG's most popular songs.

This song has entered the Hall of Fame. It is featured in the albums Period 1 and VOCAROCK collection.

"Electric Love" was first uploaded to Niconico on December 15, 2009. It is featured on an album of the same name, and is included in Vocaloid-P Data Series vol. 1. Additionally, the album Electric Love Collection consists entirely of remixes of it.

"Copycat" is an original melodic techno genre song by CircusP, featuring GUMI V3 English.

A popular theory is that it seems to be about a person having problems with their identity, whose point of view is portrayed by GUMI. In GUMI's mirror, the silhouettes of other VOCALOIDs are reflected and GUMI's facial expressions change according to them. However, when it shows GUMI's own silhouette, GUMI's face is blank, implying that she only copies the personalities of others and lacks one of herself. She may be doing this because she thinks that her significant other likes other people and tries to "mirror" them so her significant other will like her more. CircusP stated that while the information may not be official, the meaning is up to interpretation.
