Isn't it a matter of comparing file size before and after?

The compression ratio is the ratio between the size of tzhe compressed file or data and the uncompressed version. If you re-compress an MP3 file, it does not only concern the both file sizes.
You have to define, if the header information (e.g. tags etc) of MP3 files is included or not.

Pretty much, provided you are happy to include the header information in the ratio.
