I've had this problem given to me: There's an external hard drive full of music placed in different folders. The most part of those folders contain WMA files, with aswell mp3's. All that music has to be copied into his iTunes library on his mac hd. What's the easiest/fastest way to convert all those wma's to mp3, into his iTunes library? I was thinking on making a que in handbrake, adding those folders 20 at a time or so? Not sure if i have to filter out those mp3's?
