I see all these streaming devices around which will allow me to stream my mp3 music from my computer to my receiver. They all seem to be a bit 'clunky' and not give the user a good interface into their mp3 music. I have all my music stored on an extrenal hard drive. Are there any devices out there that connect to the receiver with good interfaces to control music, playlists, which I could plug my external hard drive into? Is my best bet building a dedicated pc to do this for me? What are others out ther doing?
