So... why not use VLC since it already supports what you want? :-P
Theoretical purity aside (being an everything player, transcoder, etc instead of just an audio player) it is simple to use and lightweight enough (e.g. just opened an mp3 file and VLC's memory usage was ~25MB), at least for modern PCs.
