Closes #12

While extremely similar, they are technically different soundtracks, so maybe they should be listed separately? As someone with heavy WW nostalgia, I'd appreciate that, but I can understand if it's decided to merge them

@OpenSauce04 I never played CF, but I spent many hours playing WW, and despite that, I can still say CF's soundtrack is the same as WW's. There's no reason to duplicate their menu options, or worse, add more sound files to bloat the app when CF's soundtrack fulfills WW's role perfectly.

Fair enough, as you were
