Hi, I just tested it on a Virtual Machine, and it worked, but it didn't recognize the files with extension _m.psarc for the Mac version of Rocksmith. Althought I could rename it, organize my playlists, and then rename it back, it would be a very time consuming task. So, to help the ones in the same situation as I am, I have a suggestion: When the songs are loaded, you could consider all the file name endings (_p.psarc, _m.psarc, ...), and load them all. This could duplicate the song, for example, if there are both pc and mac files are in the folder (this situation happens for the official dlc, where both files are downloaded). I don't think it would be a big problem, cause I can just ignore the ones ending in _p.psarc, and for the Windows users it would still be the same. The better solution would be considering both files as one song only, and everything I do with it is applied to both files (enable, disable, add to playlist, ...), but maybe this would be trickier to implement. My first impression is that it's a great tool, very easy to use, and it would help me a lot. Congratulations guys!
