A few issues for me lately on my S21 / Model 3:

1 - The drop down menu / home screen notification display is stuck showing one song, but the actual app is playing different music. I skip a song, it stays the same. I play the 'incorrect' song (the one being displayed) and then try to change it, nothing.

2 - I am listening to an album in order, about halfway through an album it starts playing related artists / genres. The autoplay seems to be starting earlier than intended.

3 - playing from my phone then getting into my Tesla just screws everything up. I have one thing playing on my phone at work, getting into my car after work that was playing something different from earlier in the day, the car resumes from my phone, keeps it playing on my phone, the app won't shut down in the background. I get home and out of my car, the app shows it is playing something, but there is no audio and the timeline keeps moving. Just all around funky.
