In the Karaoke Machine Refactoring updating case "choose" question!!

case "choose":
                    String singerName = promptSongForArtist();
                    String artist = promptArtist();
                    Song artistSong = promptSongForArtist(artist);
                    SongRequest songRequest = new SongRequest(singerName, artistSong);
                    if (mSongQueue.contains(songRequest)) {
                        System.out.printf("%n%n Whoops %s already requested %s! %n",
                                singerName,        ///shouldnt it be previous singername who requested the song?
                                artistSong
                                );
                        break;
                    }
                    mSongQueue.add(songRequest);
                    System.out.printf("You chose %s's %s. %n", artist, artistSong);
                    break;

in the if statement, we print out "whoops %s already requested %s" where the first %s is the singerName and the second %s is the artistSong.

However, wouldn't the singerName have the value of the singer who is trying to add the song again?

How would I retrieve the singerName who saved the song before?

The singerName and artistSong would come from the songRequest of the mSongQueue.contains(songRequest) which would be the previous singerName who originally added the song.

AJ Longstreet Thanks for answering. I'm still a little confused.

if(mySongQueue.contains(songRequest) -> here we are passing in songRequest from the line above, which passes in the singerName passed in by the current user....

Is this not true?

Thanks
