This album is one of bts' darker albums. nonetheless, it's brilliant. wings era is when bts starts to take on the more poppy side of their unique discography, such as outro: wings, 21st-century girl, and blood sweat & tears. However, the touch of edginess that makes bts, well bts, is still there and it's evident through cypher pt 4, intro: boy meets evil, and lie. The aesthetic of the wings era as a whole is very creative and as previously stated a bit darker than other albums. That is the main reason it stands out, but not in a bad way at all. 10/10 recommend! also watch the music videos associated with the solo songs and the Blood, Sweat,& Tears music video.
