1. The iTunes applet you developed in this chapter does not distinguish among multiple matching tracks with the same name. For example, you may have two tracks with the same name that were recorded by a different artist or on a different album. The user won't know that when presented with the list of choices. Modify the program so that each track provides the artist and album in the list of choices presented to the user (you can use the format name – artist – album) in the list.

2. Modify the iTunes applet so that if an asterisk is entered for the song name a randomly selected track is played.
