You have the Jukebox that you can choose a folder with the songs with the play order number in front of the file name.
The Next & Previous don't have a HotKey so you could use AutoHotkey.com to create ones and have you foot pedal trigger them and the spacebar for play/stop. If you are interested let me know and I will give more details. Else just render the songs to mp3 or video if you want the chord sheet.
