Given main(), complete the SongNode class to include the printSongInfo() method.
Given main(), complete the SongNode class to include the printSongInfo() method. Then write the Playlist class’ printPlaylist() method to print all songs in the playlist. DO NOT print the dummy head node.
Ex: If the input is:
Stomp!
380
The Brothers Johnson
The Dude
337
Quincy Jones
You Don’t Own Me
151
Lesley Gore
-1
the output is:

Length: 380
Artist: The Brothers Johnson
Title: The Dude
Length: 337
Artist: Quincy Jones
Title: You Don’t Own Me
Length: 151
Artist: Lesley Gore
