ID3 Genre 140 should be "Contemporary Christian"
ID3 Genre 140 is apparently interpreted by positron to mean "Contemporary C". LAME (lame --list-genres) shows this to mean "Contemporary Christian" and XMMS agrees. mpg123 shows "Comtemporary C". It would seem to me that "Contemporary C" is an abbreviation, and unless there is some technical reason not to use the longer name, perhaps positron should change to use the longer name.
