I am posting the full codon creation action group here in the unlikely case someone else needs this.
The action group turns a title into an alphanumeric 5 character code.
The code consists only of upper case letters A-Z and numbers 0-9. Non-ASCII characters are replaced by a single ASCII char (thus for example Æ gets turned into A instead of AE)
Shorter titles are padded by 0.
Longer titles get stripped primarily of their vowes in order to keep them somewhat legible.
The code is saved in a custom tag called "titlecodon"
Note: you have to replace the roman numeral actions near the end with whatever scheme of part X or song sequel numbering you have.
duplicates occur at about 10% in my collection (including some different versions songs)

Thanks for the help everyone.
