spotify music buttons

[31u643rjbxw353wt6q4x]

In one of the variations of the shuffle button for a playlist or songs in queue I want to suggest the idea to play a list of songs from the bottom to top. As in, the songs played after the song playing would be the ones played before. For a better explanation, if the name of the  songs playing are alphabets in alphabetical order then when the button is in motion, for suppose "song M", when the feature is clicked the next songs playing would be l,k,j,i and so on.
