Thanks for the link. I have one named ReNamer, but BRU looks far more capable.

I actually prefer Linux, but there are so many really good music-related programs available on Windows (like MP3Tag and dbPowerAmp and MusicBee) which don't really have competitors in Linux, that I tend to work on my HTPC stuff in Windows.
