This is my first work with dialogs, so it may be a little sketchy;
I used The Freeze MP3 player as a base, and have added on bits and pieces;
Original code found here http://www.hawkee.com/snippet/3255/

It currently only supports playing a single file, and only states the file name and time, but I'm working on it, sorry. =/ I'll update it as often as possible, hopefully it'll get much better. I'm working on figuring out how to add a whole directory, continuous play, etc. Any helpful suggestions would be much appreciated. menu * {
.Torment { Player }
