You could use TMediaPlayer (in system).
HTH
...Snehanshu
P.S.
Set MediaPlayer's AutoOpen property to true and an mp3 file name. Then you can play the file.

jbas,
  Here's a ready-to-use program listing to play a list of files from this previously answered question:
http://www.experts-exchange.com/Programming/Programming_Languages/Delphi/Q_20110803.html

Hope that helps,
...Shu

>>It loads the list of files from the specified path, and then shuffles them and begins playing.

>>The list is stored in a TListBox, so that you can see where it's up to.

>>btnStart starts the process.
>>btnStop stops it.

unit Unit1;
