I think thats the problem. You have to write code for each format. Wouldn't it be possible to make a 
more generalized interface? Like a hashtable with standardized names. (If not then not. The values 
have to be something similar to QVariant.) If the format supports the tag, the hashtable has an 
appropriate entry. And for writing unsupported tags are just ignored.

One could write such a thin on top of taglib, but without proper integration I don't know if it 
would play nice with custom file type resolvers.
