Intelligent mix playlist based on artist or song genre

It would be great to have an option to create an "intelligent mix" playlist based on a song or album or artist based on it genre.

Example:

1- Select a song, album or artist from the library.
2- Right clic and select an option of "intelligent mix".
3- Music to create a new playlist or queue with a number of random songs (100? 200?) based on the genre of the artist, album or song selected by the user and start playing it.
4- Optionally if the selection was a song, this song can be the first of the generated playlist.
