For sure.
I spent 6 weeks on a cruise ship gig and the bandleader never used a list. He'd "read the room" and call a tune. Sometimes he'd just start playing an intro (I,vi,IV,V) and expect us to read his mind.
The most efficient thing for me was to stay in my main library, do a keyword search, then swipe to pick the "best" chart.
Ready-set-go.
The evil-eye goes both ways...
