When you're on this site, you can play music in two ways. The first method is to click on the "launch mp3 player" graphic located in the right sidebar.

It will pop open an mp3 player that looks a lot like winamp, that you can use to play the mixes featured in the playlist. The other way of playing music is by going ot the Music page, which has a player embedded into the top part of the page. This player looks a lot nicer, lets you integrate thumbnails and artist images, however you have to be on the page for the player to work - as soon as you navigate away from the page the player will close.

Additional information in regards to the pop up player that should be noted: The player is fully sizeable - if you can't read the text in the playlist, simply drag the player by it's lower right hand corner and size it to where it's best visible to you. Also, the skip forward button requires the entire track to have been downloaded before it will skip ahead. You will see the progress bar move in the player and until it complete, the music can only played at its normal rate. Once the track has been downloaded in the background, you can freely skip around in the mix.
