You can view a large chunk of their library via their download shop e.g.: https://www.qobuz.com/us-en/shop

I do think they have some things that are streaming-only, and those might not show up in the download shop.

I can warn you that they don't have all the artists / songs I used to be able to get on YT / Tidal, but they have enough to keep me happy.

If you can't figure it out any other way, DM me a list of Arists / Titles / Tracks to look for and I'll search from my account for you.
