That sounds like a really solid approach!
As for Amazon Prime Video, they aren't really a company/service I trust with supporting the artists behind it, also seen by the fact that they're increasing their cut each year (Amazon's average cut is now at 50%, and somehow I have a hunch that they won't stop there). And I was already being generous by asking for a 50% split, compared to platforms like Steam (30%) or the App Store (30-15%) it's insulting.
Basically, for me Qobuz's attractiveness doesn't lie in offering direct downloads, as we all know there are other ways. Personally it's attractiveness lies in not having to support artist by buying tickets to their show, buying their merch, buying CDs and leaving them sealed anyways, donating or funding their sideprojects, but instead in supporting them by directly buying their product, in that case it being their music. All the other stuff is just waste I don't want.
Oh I nearly forgot but specifically Prime Video is indeed a service that allows direct movie downloads, thanks for the suggestions!
Altough......now that I've looked at it more closely and if I understood it correctly:
I'll try it out as soon as I can, but if true then this is just a horrible experience.
