Tried putting wma in the filter block and it didn't work for me. I get things like
"_______ (someone's name) gets pranked" as a wma file as well as a lot of "not associated with" wma files whenever I try to find a song.

Usually I can beat it by stopping the search and using either the song title or the artist again. It's a hassle but I have "outsmarted" Limewire by doing this.

I will try adding .mp3 at the end of my song searches and see if that works.

Thanks for the reply though, pac!
