"High resolution" audio is completely useless for listening (16 bit 44.1 kHz is the best it gets) and there is little value in lossless encodes for listening purposes too, so I don't get the point of all those "Hifi" streaming services.
If you own lossless encodes, I guess it doesn't hurt to use them even for listening as storage is cheap these days.
Speaking of which, I'd like to switch to purchasing my music though because Spotify will certainly continue on its path towards full enshittification. I want to be in a position where I own all my favourite music before Spotify will be infected with ads on premium plans. Oh and artists are somewhat more likely to be paid a little for their work that way (I hope...)
I plan to use the free YT music for discovery at that point.
I started using Spotify lite on my phone. And thankfully, there's plenty of alternative clients on desktop (such as ncspot). No crap UI elements, just playlists.
