hey guys. long time no see. anyway, I bought a new windows 8 computer and was wondering if someone could tell me how to start the music app in a batch file. or just tell me the directory it was installed in because I know how to do it I just don't know where the app was installed. so something like this

@echo off
Start "/Music.exe"
pause
:exit

thanks for your help :)
