I'm sorry to pass my own paranoidness to you, its not my intention. But truth is they theoretically CAN do it, such scripts have been demonstrated on this forum already. In the end it may not be a big deal in your case. So give that some thought.
Spotify paid is true 320kbs mp3. Spotify free is 160kbs mp3.
YT music free is 128kbs. YT paid is 320kbs, however all YT music sounds worse than other providers for some reason, this the opinion of professional audiophiles after testing.
Tidal offers lossless as well as MQA but aparently that costs more than other services. The higher quality is only worth it if you are using more expensive headphones and DAC and Amp.
