When Coffee People was just one shop in Portland, went there every day before work. (B4 internet or phones.) Loved the shop, but they played pretty aggressive rock. Not adverse to it, but first thing in the morning... Anyway was a regular. They played music via a CD player. I noticed they often silently mouthed the lyrics to the background music. Talked them into including a CD I gave them: Cecilia Bartoli "Heroines" (Rosinni). Over time it made it into the regular rotation. I noticed after a while the staff would also silently mouth the "words" being sung. Good times. Long ago.
