This assumes you’ve already run the convert spaces script. The following script will use mplayer and lame to convert WMAs to MP3s. Not much to talk about here. The wma is dumped to a wav which is then encoded in lame. You’ll end up with WMAs and MP3s of your music and you can pick and choose what you would like to do with them.
for i in `find ./ -type f |grep -i .wma`; do
mplayer -vo null -vc dummy -af resample=44100 -ao pcm:waveheader $i && lame -m s out.wav -o $i;
cp “$i” “`basename “$i” .wma`.mp3″
rm out.wav
done
