There is no proper Half-Life: Blue Shift soundtrack, as the Opposing Force soundtrack by Chris Jensen was reused. However the Half-Life soundtrack by Kelly Bailey replaces the original one in the Steam releases of Blue Shift and Opposing Force.
Trivia
The original soundtrack can be used on Steam by converting the audio parts of the WON games into the mp3 format and placing them in the proper audio folders.[1]
