As much as I want TiK ToK by Kesha to be a recognizable tune in half a millenia I know that’s not happening. Personal Jesus by Depeche Mode is one of the most covered songs of the past 50 years so that very well may become immortalized through diffusion alone. There’s a couple dozen jazz standards that could have that kind of staying power as well, especially considering their ubiquity in performance repitoires and books of sheet music.
