At 2:10, as Kendrick begins singing “I like it, I love it,” begin tapping your finger or foot along with the beat. You are in Straight Time. At 2:30, as the beat fades out, keep tapping your finger at the same tempo. Let the rhythm of the vocals and the piano guide you. Then, as the new, conflicted beat fades in after 2:35, try to hold the tempo with your finger. By 2:43, you are in Dilla Time.
