I still can't decide the best part of TIHWD
The amazing production
The catchy robotic "this is how we do"
Katy sounding so beautiful singing the verses
The "it's no big deal"
The catchy oh-oh
The catchy chorus
The beautiful "this is how we dooo" in the chorus
The fun and carefree lyrics
The inspiring bridge
The "bring the beat back"
The amazing ending
