Conversion of hma files to mp3 file format

Unfortunately, no way how to convert Sony HMA audio to MP3 format might exist, although quite a few people are looking for hma to mp3 conversion. The support for MP3s was always crappy in Sony SonicStage software and whilst it can import MP3s and convert it to its own format, it doesn't seem like works the other way.
