21.Why are only 6 songs displayed in the local playback song list?

Limited by the screen size and in order to display as many songs as possible to facilitate the operation, so it is designed to display 2 columns * 3 rows of display. Each page can display 6 songs, and page display is added (in the middle of the top of the display) to facilitate the view of the current song location. You can slide left or right on the touch screen to switch the display to other pages to complete the song viewing and selection operations.
