This code decides what tracklist each stage uses:

Most expansion stages to use Big Blue's tracklist.
Three exceptions:
Online Training Room -> FD music
P:M stages -> same music as the originals
That's one way to change it. That "01" near the end is the WWR, the 08 after it is Rumble Falls:M, and the 20 after that is Temple:M.
The other way would be to use this code: (note: you can use both)
Stage-Track Dependant Song Loader [Oshtoby]
28708ceb 000000SS
28708d2e 0000XXXX
4A000000 90180F06
14000076 FF00YYYY
E0000000 80008000
Replace SS with 5F for the WWR, 60 for Rumble Falls:M, and 61 for Temple:M.
XXXX is the ID (see the file MusicIDs.txt in the pack) of the song you want to replace, and YYYY is the ID of the song you want to use instead. So a code to replace Temple (Melee) on Temple:M with Great Bay (Melee) would look like this:
Stage-Track Dependant Song Loader [Oshtoby]
28708ceb 00000061
28708d2e 00002816
4A000000 90180F06
14000076 FF002827
E0000000 80008000
2827 is the ID of the Donkey Kong music from Subspace, and that's what the Great Bay .brstm in the pack replaces, so you'd use that.
