Eh, it\'s okay. You could add so many more options to this. I would add some more options to the spammsg, and include some method of configuration. One thing that is a bit of a hassle is the use of $sfile and searching for a directory. Why not make a list in the dialog so that you only have to configure everything at one time?
It would be even better if you could add end options such as repeat, shuffle, or even something that goes down the list of songs. A lot of people like to have the ability to be able to not have to constantly click play and select a song. I know this probably takes the originality from the snippet but it would be a lot easier to use .
