This plugin produces a shortcode that will take your tags and look for related music tracks on the Amazon download store. You can add your amazon affiliate id and set a default node for music genre.
You can choose between UK or US Amazon stores.
Just fill in the settings page and then place the shortcode where you want, it will pull the tags of the post to use as keyword seach. I use this on my music video sharing site where I only use tags for the names of the artists. If there is no music by the artist it will try and pull in tracks from your default node.
Demo site: http://ypraise.com – the MP3 player is about half way down the right sidebar. Go to one of the artists and you’ll see the mp? change according to the tag which I have set as artist name. When it is a category with no tag then the plugin will try return music tracks from your default node.
