Curious. Definitely happens to me with Spotify too, though its reactions seemed a bit more mixed bag. On the FM radio side the media player UI is working fine (once it enters the "broken" state), it just refuses to honor any station selection made - keeps playing whatever station is on, but otherwise you can move around normally.
The Spotify, if it shows e.g. some recent album art or browse buttons does the same - it just doesn't react to touching the screen over those buttons, but additionally it also sometimes just goes to a waiting loop (like it is waiting for that song change to complete that never does) and thus the UI experience breaks down otherwise too... but of course given how Spotify sporadically breaks anyway, this waiting loop thing could be an unrelated incident too.
Thanks! Indeed, so it seems:
