Here's the latest fun visualization from Google, called Music Timeline. It attempts to chart the rise and fall of different musical genres in terms of their popularity. It is all the music you're listening to!

The chart starts in 1950 and reflects data about what Google Music users have in their music collections. It paints a broad picture of the history of music that makes a lot of intuitive sense.

Google's Music Timeline can only travel back in time by looking at what from the past is popular in the present. But the most important point is that the timeline reflects what people today think of music from back in the day.
