The sorting in OnSong now allows you to toggle between ascending and descending order. For instance, if you are viewing a list of songs, you can tap on the icon in the lower left corner of the Songs Menu to view the Song Sort Menu.
This opens a list of sorting options. The currently selected sort method is indicated with an icon to the right of the text. This icon appears as an up arrow or down arrow. The up arrow indicates that the list is sorted in ascending order while the down arrow indicates descending order. If you tap on the selected option again, the list is sorted in the opposite direction. For instance, if you are sorting by Title in ascending order and tap Title again, the list will be sorted in descending order by Title. You can open the sort menu to view the sort direction of the list.
Some sort methods cannot be placed in ascending or descending order such as custom ordered lists or random order. In this case, a dot icon is indicated. Selecting these options again has no effect on the sort direction.
