Post Malone and Swae Lee's 2018 track "Sunflower" has gone platinum 17x.
That's the most times ever, topping Lil Nas X's novelty smash "Old Town Road", which went 16x.
"Sunflower" was also Post's fifth diamond (10x platinum) single, tying Bruno Mars for the most ever.
Streaming has inflated the stats for individual tracks, so you can't compare songs from now to those from the pre-streaming era.
Nevertheless, it's safe to say Post is a GOAT of the streaming era.
