@mojo771 The 15 seconds of play time for each track is clearly associated with a login issue. I've experienced this and resolved it by making sure my login credentials were correct. Did Qobuz resolve this for you?
Claiming TIDAL has a much larger catalog than Qobuz is a bit misleading. TIDAL claims to have 80M tracks and Qobuz claims to have 70M tracks. It's more important to make sure they have the titles you're interested in. That's why you can test Qobuz without a subscription as you've likely been doing since you don't seem to be correctly logged in. If hi-res quality is not a concern, then TIDAL is a fine option. But in my 3 years of using TIDAL I found that many of their hi-rez claims weren't correct as many are over-sampled CD quality tracks and then they blame it on the music publisher.
Also, Qobuz listens to its subscribers. After switching from TIDAL to Qobuz, I noticed Qobuz didn't have any Lyle Lovett albums. His albums are so well produced that I use many tracks to test the SQ of my system. I sent Qobuz an email and 2 weeks later they added all the Lyle Lovett albums to their platform. Not sure TIDAL would do something like this.
