/**
 * Create a program that implements a playlist for songs Create a Song class 
 * having Title and Duration for a song.
 * 
 * The program will have an Album class containing a list of songs. 
 * The albums will be stored in an ArrayList Songs from different albums 
 * can be added to the playlist and will appear in the list in the order they are added. 
 * 
 * Once the songs have been added to the playlist, create a menu of options to: 
 * - Quit 
 * - Skip forward to the next song
 * - Skip backwards to a previous song. 
 * - Replay the current song. 
 * - List the songs in the playlist
 *  
 * A song must exist in an album before it can be added to the playlist 
 * (so you can only play songs that you own). 
 * 
 * Hint: 
 * To replay a song, consider what happened when we went back and forth from a city before
 * we started tracking the direction we were going. 
 * As an optional extra provide an option to remove the current song from the playlist 
 * (hint: listiterator.remove()
