Naples, your roms are excellent.
Naples and/or Brad,
Here is how to fix the music.
All you need is a Hex Editor and follow this post.

I fixed it in all my Historic roms and to me is a must fix.

PM me if you have more questions.
Here are the pointers for the songs.
2c824 = Team 1, 9, 16
2c70c = Team 2
2c718 = Team 3
2c71c = Team 4
2c728 = Team 5
2c770 = Team 6
2c734 = Team 7
2c740 = Team 8
2c748 = Team 10
2c754 = Team 11
2c784 = Team 12
2c788 = Team 13
2c764 = Team 14
2c798 = Team 15
2c7a0 = Team 17
2c7ac = Team 18
2c7bc = Team 19
2c7c4 = Team 20
2c7e4 = Team 21
That is where my notes stop.
But you can follow post #8 in this thread from there.
As you can see some teams share a song and you just have to deal with it.
Whoever is in in the #1, 9, and 16 slot will have the same song.
I think a couple others after that do also.
Hope this helps.
