yes, it surely works. At least to convert them to WAV files. I don't know if Winamp can encode them to MP3, too. But if it cannot, the WAV files can be easily converted to MP3 (or OGG etc.) with the dBpowerAMP Music Converter.

By the way, if you want I can rip the audio tracks from the Glover PC version as MP3/OGG and upload it to Yousendit.
