When you import items into radio spider they default to Rename Files Copy Files (No Conversion).
To enable the conversion to Wave you must change the download method to Rename Files (Convert Audio) or Replace Files (Convert Audio).
Rename or Replace? Replace will overwrite an existing file of the same name leaving you with only 1 copy.
Rename will rename the old file adding a (0) to the file name leaving you with 2 copies.
