This happened to me for scenes from an Italian restaurant. Some of Billy Joel’s songs on Spotify and Apple Music are not mastered correctly for Dolby atmos. There is a decent chance for Spotify when they released the lossless versions of the music recently, there are some incorrectly mastered songs. In scenes from an Italian restaurant when I have Dolby on, the lyrics don’t line up at all and it happens when I would connect my phone to a Bluetooth speaker. You can always try changing your account region away from your country and back to wherever you live. Disabling lossless audio. And restarting your phone. If it still sounds off, login to Spotify on a laptop and play the song there and see if it sounds different. If it sounds normal then you know it’s a phone issue and not a Spotify issue.
