Spotify is mostly my primary music source when driving and it sounds really good to me. Surround, not stereo. My fader is placed just behind the rear cupholders just behind the front seats. I did move my truck equalizer to about 80% on the treble and bass, and moved the mid down a notch or two under half. I also made my equalizer in Spotify look about the same and made all my quality of streaming to the highest quality. Most of the playlists I bounce around to sound really good, and if you search Dolby atmos or spatial audio playlists, you’ll really hear the full capabilities of the surrounding speakers and above.
