Is there any way to filter out WMA files? When searching for MP3 music files almost every song is in the WMA format and I've never been able to get a WMA file to play because of license problems.
Short of that, is there a way to play these WMA files?

Which version of LW do you have?
For LW 5.4 or higher, go to Tools -> Options -> Search, then either Filter keywords or filter file extensions. You must put a dot in front of the file extension first. eg: .wma
If you have a different version, see How to find music as a link is provided there for filtering keywords.

Thanks, I've added the .wma file extension to the filtered formats and it seems to be working.
I appreciate your help.
