Converting WMA files to MP3

You may use "dBPowerAmp Music Convertor". It is free, scriptable, and works
well. It may be found at: 

http://www.dbpoweramp.com/dmc.htm

You'll also want the File Selector, which you can get from the same page.  
The File Selector is the only way to convert WMAs across a subtree without 
writing your own script.
