Help Finding a Single-Page Content Sorting Plugin

I’m having troubles figuring out what exactly to call the plugin I’m looking for, so I don’t know what to search for to find it. I’m sure something that does what I need done, or something close enough to make it work, is out there.

On KyleMcCarley.com/audiobooks, I’m looking for a way to add each title and audio clip to some kind of database that would then allow my site’s visitors to filter and show only clips that fall under a certain genre. I guess by tagging the clips to identify what genres or categories they fall under and then something like a dropdown menu for the user to select a genre from.

Anything out there that a WordPress guru can think of that might do something similar to what I’m looking for? Thanks!
