Lyrical Cold Open

Most songs start with an instrumental intro before heading into the first verse or chorus. Some even have a fade-in. A Lyrical Cold Open is the musical equivalent of a Cold Open, where the vocalist jumps in with lyrics at the very beginning, often adding an element of surprise or impact. Makes the song instantly recognizable to anyone who's heard it before, with the first line often becoming one of the most memorable parts.

A capella songs don't count, nor does Studio Chatter.
