Of course the biggest hack is just touching the music icon toggles it's display.Thanks again, everyone, for your input. Please definitely let me know if I’m still “missing” something.
Depend on the content you can do all sorts of other things with the display too. Using the bar at the top you can drag it up and down to 3 or 4 different sizes which you seem to understand.
Also try tapping on the album/song icon and the song title. When using USB music at least it auto sizes the screen and can even show you the album playlist or folder content depending on whats going on.
In short touch and stretch to your hearts content to see what magic lies beneath.
