What exactly is the Premium edition Proof of a Hero?

So beyond all the cosmetics of the deluxe edition the premium deluxe adds some Wyverian ears layered armour, a premium profile set, and BGM: Proof of a Hero (2025 Recording).

Are they telling me that without paying an extra £40 I’m not getting the newest version of the song? Or are they saying that I will still have it in game at scripted points but can also have it playing in my room like in Iceborne or in menus or whatever?

Because just saying BGM: Proof of a Hero (2025 Recording) tells me very little and seriously sounds like they’re saying that if I want THE monster hunter song in my game or at the very least the latest version I need to buy not just the deluxe edition but the £100 premium deluxe edition.

I can’t find any clarification anywhere, anyone know? My apologies if this has been asked before.
