I have never heard of quobuz before, that’s awesome that they offer that much. The main reason I use deezer is because of my dj business. I can create the Playlist in deezer, then download the whole list at once with deemix for gigs. I’ll have to see if quobuz has a download option.
I checked them out and it seems like they have great selection, but I was turned off by their shady marketing. On their home page it says $10.83 per month in bold letters. Then underneath in small print says “for a 12 month no refundable subscription with one payment of $129. Monthly subscription is $12.99/ month” not cool.
