The track should be “sufficiently” xenharmonic, occurring in Billboard Hot 100 (as an arbitrary measure of mass popularity—advice me a better one) listings before 2024-01-01. Xenharmony (for the sake of this question) is the usage of musical tunings other than 12edo. Terms what substitutes for differences from 12edo might be stretched so decide at your own risk if I consider the track you think is far from traditional 12edo usage as plain 12edo.

If I find a way to externalize feelings in the future, I could make the notion clearer. What I definitely won’t treat as xen is trolling like “this piece is in 1200edo but uses steps 0—399—708 for a major triad” as this is quite indistinguishable from 12edo major triad if instruments allow slight detuning. So if the sound is quite strange to an untrained ear, this might be it—also, consult what the artist says about the tuning, as it’s common now to describe not only that a piece is xen/microtonal if it is, but also to name tuning(s) or frameworks used.
