It's not a matter of "just" putting the old music in, broskis.
You have to edit each event where the tracks are used and update the Play BGM command.
If you just threw in the old Cheshire Cat track as it was in the older copies of the game, a genie wouldn't come out of a bottle to update picrel for you.

Alternatively, you can paste the old tracks and then give them the filenames of the new ones, which is also valid and what I imagine that hero without cape did.
