            nextIndex = (int)song[2];
            songName = (string)song[3];
        }

        AudioEngine audioEngine;
        SoundBank soundBank;
        WaveBank songCollection;
        Cue song;

        protected override void LoadContent()
        {
            audioEngine = new AudioEngine("xact.xgs");
            soundBank = new SoundBank(audioEngine, "mus.xsb");
            songCollection = new WaveBank(audioEngine, "mus.xwb");
            song = soundBank.GetCue(songName);
        }  
    }
}

Debuger says
System.ArgumentOutOfRangeException: “Stream length must be non-negative and less than 2^31 - 1 - origin. Arg_ParamName_Name” on this line:

soundBank = new SoundBank(audioEngine, "mus.xsb");
