Unnecessary, I guess?
Twinkle was fun but to be honest I wish SM had taken Baby Steps, OMG and Love Sick/Checkmate and stuck them on The Boys in place of My J, Sunflower, Mr Taxi (the Korean version is a waste of three minutes of my life), and How Great Is Your Love, and then saved the rest of the tracks for Soshi’s Korean comeback or the new Japanese album.
My favorite thing about TaeTiSeo is Seohyun, who should just be included more because she is the greatest, but I really wish they’d just given Taeyeon/Tiffany/Seobaby a rest. Girls work hard enough as it is and need a break.
