"All-round Cheat Key," SHINee Key (a member of SM Entertainment) wrote the lyrics for his new solo album.

Key's first mini-album, which will release on September 27th, includes a total of six songs, including the title song "BAD LOVE," as well as "Saturday Night" and "End Of My World" written by Key himself.

The new song "Saturday Night" is a disco genre song with a strange harmony between the glum synth pad and the rhythmical baseline that gives the sensibility of the 80s. The lyrics depict the emptiness of a heart that cannot be filled even if there are many people around or in noisy places.

In addition, Eighteen (End of My World) is a warm-hearted pop song featuring appreciation and comfort for childhood when they were hurting each other with poor behavior, attractive contrast between the soft intro and the soaring chorus, and vocal group. Heritage participated as a choir to heighten the emotions in the second half of the song.
