SongNode currNode;

SongNode lastNode;

String songTitle;

int songLength;

String songArtist;

$//$ Front of nodes list

headNode $=$ new SongNode$()$;

lastNode $=$ headNode;

$//$ Read user input until $-1$ entered

songTitle $=$ scnr$.$nextLine$()$;

while $(!$songTitle.equals$("-1"))\{$

songLength $=$ scnr$.$nextInt$()$;

scnr$.$nextLine$()$;

songArtist $=$ scnr$.$nextLine$()$;

currNode $=$ new SongNode$($songTitle$,$ songLength, songArtist$)$;

lastNode.insertAfter$($currNode$)$;

lastNode $=$ currNode;

songTitle $=$ scnr$.$nextLine$()$;

$\}$
