Json file into javascript file

Hi everyone, I've been trying to modify an html 5 audio player that works using javascript for quite a while now, but i'm no good with javascript really and I've given up...

Here is the player I'm trying to modify;

The player works by bringing in the playlist from a json file. The json file is where the attributes of the title and the the associated cover image are defined. There is also a space in the javascript file where you can include a link to LastFM, but this is not variable. I need this link to be variable, as i plan to use it as a link to each songs itunes page. That link will be defined in the same place as the 'title' and 'poster' attributes already are, in the json file.

You can download the player from the page above and see it all for yourself. At the top right of that page there is also a link to download the uncompressed javascript file. If you could modify that file so that I can see what you've done and learn from it that would be much appreciated.

I look forward to hearing your quotes. I'm hoping it's not going to take some of you very long at all. I will pay immediately once I've seen it working on my side.

Kind Regards,

Jordan
