/sigh Played this game again and as always loved it but now that you have lost some of the songs it is quite sad. Honestly if you could not use the original then would have been nice for you to add a substitute for them.
The ride in the limo is just silent and cold and lexi singing at her piano during the romance just some generic music on loop the whole scene. Please if you ever feel up to it please patch in some other music for the locations where songs where lost.
Or at least take this as advice for the next game you make if you do, if something cant be used please substitute with something fitting that can be.
