Rearranging mp3 filenames starting with The/A/An

[Narcissus]

I am attempting to get my mp3 collection's filenames all the same format, but half of the filenames start with "The" or "A/An". An example is as follows:

Current filename: Michael Jackson - The Way You Make Me Feel.mp3
Desired filename: Michael Jackson - Way You Make Me Feel, The.mp3

What would the proper way to go about this be? Any help is greatly appreciated.

The , A , An : are they always after - ?

For this particular instance, yes, since I'm addressing the song names right now. After playing with it awhile I think I actually just figured it out.

Match: (.+) - (The) (.+)
Replace: \1 - \3,\2

That seems to have worked from what I can tell.

Yes, that's correct. You should be able to use also

Match: (.+) - (The|A|An) (.+)
Replace: \1 - \3,\2

that is, match The or A or An after -
