Where can I find the soundtracks to the Left 4 Dead games? [closed]

Where can I find Left 4 Dead and Left 4 Dead 2 soundtracks?

Do they officially exist?

There is no official soundtrack, as far as I know, but you could try the Left 4 Dead wikia Soundtrack page, which has all the different songs from both games arranged in nifty little youtube clips.

For posterity _{(and those without good net)};

You can find them in your game directory, most of the actual music (you can find all the other scores and sound bytes in these folders) resides in;

left4dead2\sound\music\cpmusic
left4dead2\sound\music\l4d2

These are subdirectories of your game directory which would normally be located at;

%programfiles%\Steam\steamapps\common\left 4 dead 2
