Strange issue with jQuery's slideUp/slideDown

Question

I use the following code on a website:

  // show tracks
  $('.content-playlist .track p').live('click', function() {
    var player_handle = $(this);
    $('.content-playlist .track .player').slideUp('slow', function() {
      player_handle.next().slideDown('slow');
    });
  });

Which should first closes any music players on the site (if any) and after that open the selected one.

Clicking the first track works as expected.

However I'm having a strange issue:

When clicking on the third track it opens, closes and opens again. (not what I want)

An example is online @: http://www.psykotaktyle.com/index.php?page=playlist

I just cannot find out what´s wrong with my code. Any help is much appreciated!

EDIT

Tested with Chrome (v13), IE9 and FF4
