I've not been using this for very long but it plays back the files that I've tried very well. AFAIK this is the only player of it's kind for the Mac so I'm very grateful that this exists, good work :D

The interface is simple and easy to use, although it would be nice to see a Playlist perhaps?
Also, at first I thought the + and - buttons were for the volume rather than the next sub-song buttons.

There also seems to be a 'Conv' and a 'Ripper box', which currently serves no purpose? Perhaps in a future release the app' will support converting the tunes?

Otherwise, it works well, thanks very much :)
