So I made these forever ago but never uploaded them for use by others. I wasn't happy that Dracula's Castle didn't have any Castlevania music, so I replaced every track with songs from Castlevania: The Arcade. There's a couple other tracks in here, as well as fixed info.pac and mu_menumain.pac files so they have the correct song names. It also has all the regular tracks from Project M in there so be warned of that.
Song list:
Luigi's Mansion Theme - Vampire Killer (Arcade)
SMW Castle - Simon's Theme (Arcade)
Airship - Wicked Child (Arcade)
Tetris Type A - Bloody Tears (Arcade)
Tetris Type B - Beginning (Arcade)
MOTHER 2 - Pollyanna (I Believe In You)
Cavern - The Stains of Time (Maniac Agenda Mix)
Underground Theme (Super Mario Land) - MetaI Mario (Super Smash Bros.) [I did this one because sometimes it would load up the underground version of the stage, so it needed the proper replacing. The reason it's spelled "MetaI" with an I instead of an l is because you can't have two of the same song name]
All properly loop (or as best as possible, in the case of Stains of Time), so you should all be good to go.
