I just got rid of MS Windows after using it for the past 15 years (my whole life) and all my music is in either mp3 or m4a. I'd like to use ogg from now on. Does anyone know of a good audio conversion program (preferably graphical) that can convert mp3 and m4a (I dont mind using two different programs, but it'd be nice if they were one) to ogg? Thanks in advance.
P.S. I dont mind if its proprietary, and possible legality issues don't concern me.
