Ah yeah but that's always the case. Was mostly just surprised my response to 27 number ones was "really, only 27?!"

Looks like the hot 100 is more confusing than I thought; I see I Want It That Way by the Backstreet Boys only peaked at 6 because it somehow only came out after its peak in popularity, whatever that means (maybe it was only a music video for a few weeks or something or not physically available or something?)

US #1 or not, the song is an enduring classic. It has remained in the top 200 on at least one Spotify chart since 2015, and probably as long as Spotify has existed.
