composer field question

mp3tag shows composer as "Bach".
foobar2000 shows composer as "Johann Sabastian Bach".
I am kind of lost on this one...
Anyone have any thoughts?

The reason I ask is that foobar2000 shows the cd under "Johann Sabastian Bach" not under "Bach" where I wanted it...

EDIT: whoops, it was a music server problem. For some reason it didn't see the file updates. A re-scan of the library fixed it all up.
