Hi @Marten H
Welcome to the Sonos Community!
Sorry to hear about this issue you are having with tracks on Tidal ending before they are supposed to.
In my testing, I have been unable to reproduce this behaviour either with the Laurie Anderson album mentioned, or with Jackson 5 and “ABC”. The former played without gaps.
Therefore, I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.
Before doing so, however, I recommend that you first try rebooting your router by switching it off for at least 30 seconds, and please try removing Tidal from your system and adding it again too:
Remove a music service account from Sonos
Add a music service to Sonos
I hope this helps.
