Best Program for Playing Music

anything...whatever the file is saved as and opens up in...WMP, quicktime, sonic stage,

Im actually thinking about going back to WMP. Im jsut so used to it.

Winamp.

Is there any way to play songs at half speed using winamp?

Use this plugin for it http://www.winamp.com/plugins/details.php?id=12689

The pitch control and tempo control are independent from one another so they don't mess eachother up.

^ many thanks buddy
