Just testing whether the mp3 player script works ;). Just click on the play button in front of the song name and you should hear the music. If you don't see the play button just give it some time to load, it should load eventually.
Dirty Window by Metallica
BYOB by System of a Down
Question! by System of a Down
Hypnotize by System of a Down
You're Beautiful by James Blunt
Lady Marmalade from Moulin Rouge
Update: To use it in your blog all you have to do is to add the following code somewhere between the head tags.
After adding the above script, whenever you specify a direct link to a mp3 file in your post, then the script will automatically detect the mp3 link and will add the play button in front of it.
The Direct link should be something like this
<a href="http://somedomain.com/somesong.mp3">Some song</a>
