New ingame music

[Widow17]

hmm to see if it might help with performance i decided to completely reinstall CLOD. I let steam remove it and then downloaded again. When the download was ready i wanted to install it again, but when the window opened to allow installation i remembered i wanted to do something else first so i clicked no´. To my suprise the game launched though i presse4d no and when i came to the mainscreen i notice a different backround music. Not this stupid music with the drums beginning but a very nice song with piano and strings. Then i quit game, becausei wanted to have it installed correctly ( press ok in install screen). After doing this (steam installed a little stuff, no idea what, was very short) the old backroundmusic was back. Where has the new one gone? i dont get it......
