I have attached the BeatStore plugin so you can see what they do to modify the Easy Digital Downloads post type. I then want to use these custom fields that were added to the Easy Digital Downloads post type and make a wordpress plugin that filters and sorts Easy Digital Download posts and integrates with the website music player. There exists various post filtering plugins for Easy Digital Downloads so some of that code might be able to be copied and forked from existing plugins but I want to filter posts in a custom way, not yet done, so a custom plugin will be required.

Aside from the custom plugin and adding extra functionality to Easy Digital Downloads, I am having compatibility issues with Easy Digital Downloads and Ajax preloading pages on my site which is required for the website continuous music player to work and I would like to find a way to make the website continuous music player work with Easy Digital Downloads without having to disable Ajax preload on those pages.
