With the player beside the map, like, shuffle, repeat and lyrics move into the nav bar

The nav bar's pill carries them while the player is docked, with its dock button in the
same place to close it, so the player itself is just the cover, the song and play/skip.
The player's own close button, which sat over the corner of the cover, is gone.
