Hi @Adam_Casey,
Thanks for reaching out and I really appreciate you providing all of the useful info in your post (including logs and System Output testing), this would have definitely been out starting point for troubleshooting so we saved a few steps of data gathering here
Looking at your logs, I am seeing the following when you try to play TIDAL content:

As you may have noticed, the buffer is rapidly accelerating towards 0%, which is not good. This could indicate a few things: either the network connection is dropping, or the requests are not going through fast enough, or there’s an issue with your Core’s HDD/RAM and reading/writing data is not occurring fast enough.
As @Mark_Apperly suggested, my first thought here would be to change your DNS servers to Cloudflare / Quad9 / Google DNS and see if that’ll help. You should also try temporarily disabling DSP to eliminate this as a potential variable (while testing).
Do let me know how the DNS test goes and if the issues are still the same, just let me know and we can take another look, thanks!
