Imo JYP really ruined Twice with all the wrong decisions:
1) Long dragged out promo for The Feels their breakout English single
2) Scientist, a super underwhelming song, chosen as the title track over The Feels
3) Celebrate was made a Japanese only single, and TTT being title track instead
Isnt it obvious that The Feels > Scientist, Celebrate > TTT
Celebrate has all the elements of a hit song, and it has a much stronger Twice vibe than TTT. It has the original song structure of Twice, it is fun and also meaningful - a celebration of their anniversary, it is super catchy. TTT isnt that bad but the chorus is too short to really capture attention.
