Show full screen song player when start playing song

[barbeau]

Is your feature request related to a problem? Please describe.
Currently when you tap on a song, it loads and starts playing in the bottom sliding panel bar. I believe it does this to allow ease of browsing and to minimize back and forth if you tap on the wrong song. Google Play Music has the same behavior.

However, Spotify, YouTube Music, and Amazon Music always jump straight to a full screen player when playing a song.

Describe the solution you'd like
We may want to change this so when you start playing a song the sliding panel expands to full screen to show the playing song (instead of remaining in just the bottom bar).

Describe alternatives you've considered
Do nothing - leave as-is.
