Song recommendations to test the hi-res functionality?

hi! new user (for ethical reasons) but I've seen a lot of hype about the hi-res functionality of Qobuz. Problem is, I don't know if I have the tech (or ear talent!) to actually notice the difference between ​a hi-res song on Qobuz and whatever res sp0tify uses. I'm sitting here comparing the same song across two platforms and can't tell the difference 😅 not a big deal, but just for interest - any tips on what to listen out for, or a song where the difference is more obvious? or maybe I just need the fanciest possible headphones?!
