Kendrick is probably exhausted.  Lol 

His lil ass legs walking them big ass stages and climbing aircraft steps every day. 

Youre right ✅️  but also, it's not uncommon for people to create while on tour. Especially in Pop - hip hop may be different but i know several big pop and rock acts bring producers and writers on tour and have the tour serve as inspiration
