How can I simplify downloading and playing HD audio?

I would like to make it easier to download audio albums from HDTracks to a storage device like a usb flash drive and then stick it into a box that has HDMI out to my receiver. This box needs some type of lcd screen that can display the content of the drive and allow me to navigate to play any album I choose. A random play function would be nice also. The HDTracks come in the flac format.

Any devices come to mind?
