I could instead derive my class from Song, and use a cast.

can both mySong.Artist and mySong.Artist.MaxLength yield values? If so, how do I implement this?

public class LimitedString {

   private string _value;
   private int _maxLength;

   publlic LimitedString(string value, int maxLength) {
      _value = value;
      _maxLength = maxLength;
   }

   public string Value { get{ return _value; } }
   public int MaxLength { get { return _maxLength; } }

   public static implicit operator string(LimitedString limited) {
      return limited.Value;
   }

}

How do I "add" a property to the existing property of an object? Is that allowed syntactically?
