Playing one song after the other one's finished

Hey everyone! I need your help again, last time I promise haha!
I’m trying to auto play multiple songs in a row so when a player is in the game (level one) The music plays in order, and then repeats the list. I got it to auto play one song and loop it but it does not play the other songs.
Any Advise?
