And it came upon me wave on wave, you're the reason I'm still here. Am I the one you were sent to save? And it came upon me wave on wave.

About This Quote

Wave on Wave means a series of events; it means the opposite of a eureka moment (something where it all hits you at once); it means it hits you slowly, and over time, a series of cascades or waves. So when Pat Green says "it came upon me wave on wave" he means: "it came upon me as a sequence, one after another and then after this long series of events; I finally realized it." So the meaning of the song wave on wave is simply an event after another event after another event that finally makes us learn something.
