YouTube has launched a new music portal called YouTube Music. The site lists the most popular music videos hosted at YouTube and the most popular music videos of particular genres. Opposed to the already exisiting music portal YouTube Disco, where everyone may create own playlists, YouTube Music is a portal for easy listening and viewing music videos. To do so beside the headlines of top videos and genres a link to start playing a playlist is provided. For more visit YouTube Music.
