Haha! Emojis gone rogue!

"I'm not using the terms "tonicization" and "modulation" in the same way you would when undertaking an analysis of Baroque or Classical music"

Well, yes and no. They aren't just terms for analyzing baroque or classical music (hence my Taylor Swift nod). "Waste" has a V/IV tonicization. It's in D, we get a D7, which "tonicizes" the following G. That's just what a tonicization is, plain and simple, a fancy term for when a secondary dominant happens. However, modulations of the sort I'm describing are certainly almost exclusive to "classical" music styles. So I think I see what you're getting at, you kinda used it like a ratio. In a style of music (baroque for instance) where key changes happen very quickly and frequently, modulation and tonicization mean one thing, but in a style of music where one key is vamped in for sometimes 15 minutes, the usage of those terms then becomes adapted to account for longer spans of time as well. I can get behind this. (emoji intended)
