Music player not working?

[SteveCRM]

why doesn't this play? (its not because it closes because it does the same in a windows program)

    cout<<"Loading File...."<<endl;
        mciSendString ("open C:\lit.mp3 type mpegvideo Alias mpeg", 0, 0, 0);  //opens file
    cout<<"File Loaded...."<<endl;
    cout<<"Playing File...."<<endl;
        //mciSendString ("Play mpeg from 0", 0, 0, 0); //play file
        mciSendString("Play mpeg from 0", 0,0,0);
    cout<<"File Played...."<<endl; 

why won't it play? that is a valid file...
