Media content type?

We will have around 200 files and we want them to be dynamically selected by means of a view based on the type (video, audio, docx, pdf, xlsx), words in the title and description as well as a hierarchical taxonomy. Once a file is selected out of the view, we want it displayed or played (if audio or video) right from the page (i.e. not having to be downloaded and then accessed as a separate step). The most important part is the onscreen list and selection. We could live w/o the player part.
