The #Google Music Timeline: The job's not quite done!
A quite beautiful way of viewing and searching music genres and artist across a timeline. This is from Google research, but imagine if they applied this to your Apple iTunes or Spotify playlists. It's a really engaging way to view and explore any music catalogue. Take a look for yourself.
Drilling down by clicking into the genre of choice, displays sub genres and artists. This is a principle that could apply to any type of search...maybe that's what Google are thinking?
