All you have to do is download the Sony SonicStage software, import your omg files and burn your omg files to CD via SonicStage. SonicStage converts the file to a cda (Track) file. Now you can convert the cda files to mp3. Of course you will need another type of software to do this. I use Sony Music Studio, but I am sure you can use any other type that can access a cda file.
As you can see this is a two step process, but it works.
