That’s one of my favorite features, sometimes I’m too distracted driving or doing something else to manage Spotify, but that doesn’t mean I want the background music to stop entirely.
But for a developer building a custom listening experience it needs to be completely optional.
Right now you literally can't build an experience that plays just one song and stops after because "radio" automatically kicks in. You need to do crazy hacks to pause the current song before it ends or enqueue a silent track and intercept that, if you don't want to occasionally hear a small bit of an unwanted radio song before correcting.
