I don’t entirely agree with you. Comparing the same song in MP3 or FLAC on the factory-fitted audio system in my car (2023 Skoda Octavia Combi) already makes a huge difference. Of course the difference is smaller when using 256 or 320 kbps MP3, but even then FLAC just adds that extra bit of depth and “openness” to the music
There’s one thing that’s preventing me from doing exactly that and that is, as a non-native English speaker with tinnitus, the constant struggle to find good subtitles that are properly synced. My lazy ass just wants to enjoy a movie at a normal volume without having to force myself to be super-focussed in order not to miss the whole goddamn plot of the movie.
