Welcome to OSX!
I am probably one of the very rare few who actually uses the LW media player in OSX! lol
Most people just use iTunes for listening back music. Let's face it, if you have the option ticked in your LW Preferences, iTunes will copy the file to its own library as soon as any audio file has completed downlding. So ... why 'tie up' LW's resources by using the media player when you can listen to it using iTunes instead. Please downld updated iTunes version from here:
http://www.apple.com/itunes/download/
Go to LW's Preferences>iTunes>importing & tick enable iTunes importing & press Apply button. Also, go to LW's Preferences>Player & untick option to use LW's media player & press Apply button. After this everytime you preview or launch a song iTunes will open & play the song.
By the way, even though the following link is intended for windows users it might be wise for you to check it out:
