The WBC1 menu music doesn't play on my Windows XP or Windows 7. I can hear the button sound effects. Running in compatibility mode for Windows XP doesn't work for me.

I also had this problem, It seems like the after battle music is missing as well. It's probably not related but I seem to recall the original version didn't play those tracks if you played without the disk in. Maybe it's a side effect of them removing the copy protection?
