Ace-High MP3 WAW WMA OGG Converter is a 'easy to use' converter program. 
It converts MP3 WAW WMA OGG to MP3 WAW WMA OGG (and let you change bitrate). 

If you choose to register it (to convert more than 10 files at the time) with the keygen, i recomend that you choose a name that is longer than 6 letters (if its to short it wont work). Just don'æt give up if its not working the first time.

My first torrent in this genre, so if you want more info, just ask!
