What will be the advantage to use the Subtitle filed, instead of append the title?

Do you know an other common media player application which supports the subtitle field? I know non.
Even EasyTag does not support it.

I have just found this:
http://id3.org/iTunes

"Currently most users write their refinement remark into brackets within the title frame, i.e. "Back home again (live)" or "Cannot stand my mood anymore (Pac Man Mix)". In my opinion, we can also leave without this being implemented. "

So It looks like this is a highly non interoperable field.
I think we should not encourage the user to use it for info like (live) or (radio edit).

Maybe it could be useful for other interesting infos.

By the way: There are other more common fields that are also ignored by Mixxx:
* Original Artist
* Sorting fields
* Copyright
* Url
* encoder
