Indeed, my player -- as far as I can tell -- doesn't know a thing about 
id3 tags. You are probably right that supporting the lowest common 
denominator -- id3v1 -- is the way to go for portable players. As soon 
as I wrote the above I began thinking alone those same lines. In that 
case, mutagen isn't really appropriate: it cannot write id3v1 tags at 
all. One possibility would be to use mutagen to read the tags but 
another library to write them out; the existing ID3 module, for instance.

Agree 100% :)
