This mod replaces the menu music with the Piano Lifeguard Theme, A very beautiful, sad, and quit song. This is a great addon if you want your zombie apocalypse scenario to be a sad, emotion, dramatic, oh why does God hate me kind of thing like left 4 dead 1 was. Instead of being a minor inconvenience, possible adventure, and this chainsaw starts noise hell yeah, we be killing good tonight kind of attitude that left 4 dead 2 has. As one fan puts it, " It brings back that wistful, sad, L4D1 aura" Incase I haven't mentioned it yet, this song was taken from another zombie game: Dead Island IMPORTANT: It is a quiet song. you must have game and music volume at full for intended sound. Now if this is to quiet for you guys, let me know in the comments and I'll upload a louder version.
(This Addon, according to commenters is only working on about half the people)
