Most of the Music Database entries are the same from one model of a given line to the next, so the work that was done on the PSR-E433 Music Database song names should apply to the entries in the PSR-E453 Music Database. Only the new entries still need to be deciphered-- although it's a good idea to verify whether the older entries were deciphered correctly or not.
I tried to make a list of the new entries by comparing the PSR-E453's full list against the work that was done before. The new entries are given below, but someone should go through and verify that I didn't leave any out or include any that were already in there. I've made suggestions for a few of the songs, but they're just guesses based on the cryptic names.
