A really great performance does ListAndPlay, a search engine for music videos using the instant search feature. The service is able to display music videos already while typing a name or a title into the search form and even to start these videos immediately. This is impressing and has a touch of future television. And indeed an interface described by tv is available at tv.listandplay.com.
The difference of these both interfaces is the way playlists are created, which happens at the homepage by searching for music videos and adding these videos by a click on a button. At the tv interface just one name or a title is needed to create a playlist of 150 videos of similar music, which is enough for hours of music aka music television. To navigate the videos a couple of buttons are available located below the search form.
