 *** REPEATED NAMES EVEN USING 4-LETTER (3rd letter is last letter of first name) CODES ***
(the top one maintained the supposed name while the one below changed the last letter to the next in alpha order in caps)
(to improve it even better, could use the first and last letters when there are only 2 chars. But one more rule makes 
    it harder to input data).

 *** REPEATED NAMES IF USED 3-LETTER CODE ***

 *** REPEATED NAMES EVEN WHEN USING 4-LETTER CODES ***
(I thought of using the last letter of the first name after observing the list below, 
    it would help eliminate a few, however, it'd take time for the user to think before 
    entering the artist code and possible cause confusion and invalid data.) -> now referential integrity can be enforced so...
