The term "dated" more so is used to describe a song that sounds like it just missed a recent trend, not that it sounds like it belongs in another decade where the musical soundscape was completely different. Because it does sound a bit like something that would have been released a couple of years ago when this kind of EDM-influenced pop was really riding high, I absolutely get the "dated" comments here.
Side note, but why can't stans here and there just accept it when people outside of the fanbase may not be ******** themselves over their fave's new song? If you like the song, great, enjoy it! If people don't and are constructively expressing valid reasons as to why they don't like it, I don't see why there's a need to get defensive or childish by turning this into some uncalled for stan battle by bringing other artists into it.
My favorite thing about this song is it shows that she's willing to experiment and be versatile and isn't "above" straight up pop like some people at her vocal level might be. That's not directed at anyone I'm just praising her for being cool haha
