Aoe 2 DE return of rome lobby music

If I understand this thread

Where is music for RoR located?

Does anyone happen to know where the Return of Rome music files are located in the game directory (or what the file path is for the music files)? I have been trying to replace some of the Return of Rome music but I have had no success.

correctly, the answer is that all Return of Rome music is in a single .pck file – presumably AoE2DE/wwise/en/Pompeii.pck

(I have no idea how to use/extract music from this type of file.)
