Best method for "firstname lastname" to "lastname, firstname"

[jcdrisco]

My apologies if this has been asked and answered, but I've ripped my classical music collection with the composer tag organized as "firstname lastname" I'd like to sort the minimserver output by last name--so that "Johannes Brahms" is under "B," but view it, if possible, as "Johannes Brahms," not "Brahms, Johannes"

The "reverseName" option does the reverse of what I want. I'm thinking of using a batch editor such as mp3tag to redo all the composer tags as "lastname, firstname," and then use the "reverseName" tag option. (I didn't do this originally because I'm not sure the ripping program I used at the time initially had that option). Is that the best way?
