The 8 images above are different music channel websites.
On all of them they use imagery as the main body of the site. They all have a main focus on the videos of the music and then further down the page or on another page is the charts or what can be played on the channel. On all of them they have a rectangular grid system. Nearly all of them have dark backgrounds with one vibrant color on top to stand out. My favourite design out of these would be the Kisstory website as the four blocks bounce because of the different music that is playing.
Below are other examples of TV channel websites.
