I’ve been using uk.7digital.com for multiple years. Quality is great, I can download FLAC, and I find their prices tend to be a bit lower than Qobuz (at least for the music I tend to listen to).

There’s been an occasion or two where the music I bought was no longer available (they don’t hold the distribution rights in perpetuity), but I download it right away and keep good backups locally (same as I would with my old CD rips because CDs don’t last forever either).

I accept that, as with anything digital, I’m purchasing temporary right of access and take steps to secure it in case that access is removed or the company goes out of business.

[Edit: nothing against Qobuz, I’ve just been happy with 7digital for years and I don’t see Qobuz offering me a compelling reason to switch or 7digital offering me a compelling reasons to leave.]
