Youre pulling my leg, right? hee,hee, no way! Anyway, if anyone would like to know how to do it with your software, you can rip the songs then convert to .WAV files and then use Windows WAV Player to run the songs at various speeds in forward or reverse, and jump with the slider control. Then you can easily hear the back masking.
That is if you can find a program to convert it to a .WAV the the Windows WAV player can use. Dammed if I can get it to work... go to the run command and type sndrec32 to open the program to play songs backwards.
The guitars are crystal clear, I can hear the notes better than on the original or the live version.
