Red Staper's Music Melomania Mod (RSMMM) is an add-on for Soundtrack Editor/Forked that adds 169 stock-alike music and 57 ambient sounds in order to further enhance and add a bit of groove to your Kerbal Space Program experience. All tracks are instrumental, some are whimsical, some are loungy...all approved by the Kerbin Instrumental Sound Society (KISS).

Reggae/Dub, Funk, Jazz, Disco, World, Classic Guitar, Latin/Brazilian, Blues, Mellow Rock, Loungy Stand up Bass Types, Groovy Space Rock, Futuristic Modern Spacey Stuff, Chilling in Space Ambiances, 1960s Star Trek TV Series sound-alikes, and a splash of Austin Powers-ish cutscene music to keep your Kerbals (or you) from going daft on long missions.

Installation:

You need to have Soundtrack Editor Forked already installed in your root KSP folder as per instructions for that mod.
Extract the entire contents of this zip to the KSP root folder, merging the Licenses, Music, and Playlists folders with the existing folders (RSMMM will not overwrite anything in these folders unless you have installed an earlier version of this mod).
Open the Playlists folder, make a backup/rename your current playlists.cfg file and rename RS playlist.cfg to playlist.cfg.
Launch KSP and enjoy the new instrumental and ambient tracks!
