Music modules would be added to the resources as "DATA" so basically, if you use that program, it might have an option to extract Unknown resources, or "Data" resources...if you get that far, then you're in luck
And after getting that far, you will have to basically, either open the file up in a text editor and by reading the small words, or combination of letters at the beginning, you might be able to figure out what format and rename it with the proper extention, or use the adequate program.
