Many people have said that they like the style of this website, and so now available is the Live Radio on the Internet wallpaper.
There are currently 4 available - more may be added over time, so keep checking.
Select the type and size you want, and after downloading simply unZIP to your Windows folder/directory or run the executable file, depending on the version you have downloaded. If you are unhappy about unZIPing, use the self-extracting (.exe) version, which will by default unZIP to your Windows folder/directory when run - this wallpaper will then appear in the list on your system.
The backgrounds actually look like that on this page, but the fine detail cannot be seen in these pictures, appearing as black instead.
