Problems with Karaoke class

Hi. I've picked up some errors with my Karaoke class.

import com.teamtreehouse.model.KaraokeMachine; //error here
import com.teamtreehouse.model.Song;
import com.teamtreehouse.model.SongBook;

public class Karaoke {
  public static void main(String[] args) {
    SongBook songBook = new SongBook();
    songBook.importFrom("songs.txt");
    KaraokeMachine machine = new KaraokeMachine(songBook); //2 errors here
    machine.run();
    System.out.println("Saving book...");
    songBook.exportTo("songs.txt");
  }
}

Errors:

KaraokeMachine is not in the model package/folder so you need to remove "model" form the import Statement, I believe.
