How Old is Your Brain?

Some of you might have seen this little flash-based brain game. Whenever my mother forwards me something, I have to assume at least half the moms in America have already seen it. Nevertheless, I thought it was appropriate for the _floss for two reasons:

1) If you haven't played the game, you'll probably dig it and
2) We're giving away two cool new books to two lucky winners

Here's how you play. Click the link and then click start. Numbers will appear and then disappear. Your job is to memorize the numbers' respective positions and then click on them starting with the smallest and proceeding on up in order to the largest.

After 10 rounds, the program will calculate your brain's age.

I tried it a couple times and scored a 27 and then a 24, which made me feel pretty good since I'm practically twice that.

Post your lowest score in the comments, along with your actual age. We'll give away two books*: one to the first person with the absolute lowest score and one to the person with the biggest difference between actual brain age and brain age according to this fun game (please post your math, too).

All we ask is that you tell the truth, of course"¦ because what fun would it be if you embellish or stretch or otherwise warp the actual results?

* The two new books I have sitting on my desk right now, waiting to be claimed, are: Adam Nimoy's just released 'anti-memoir' My Incredible Wonderful, Miserable Life (yes, son of Leonard) and Christopher Cerf and Victor S. Navasky's Mission Accomplished! How We Won The War In Iraq.

New AI-Driven Music System Analyzes Tracks for Perfect Playlists

Whether you're planning a bachelorette party or recovering from a breakup, a well-curated playlist makes all the difference. If you don't have time to pick the perfect songs manually, services that use the AI-driven system Sonic Style may be able to figure out exactly what you have in mind based on your request.

According to Fast Company, Sonic Style is the new music-categorizing service from the media and entertainment data provider Gracenote. There are plenty of music algorithms out there already, but Sonic Style works a little differently. Rather than listing the entire discography of a certain artist under a single genre, the AI analyzes individual tracks. It considers factors like the artist's typical genre and the era the song was recorded in, as well as qualities it can only learn through listening, like tempo and mood. Based on nearly 450 descriptors, it creates a super-accurate "style profile" of the track that makes it easier for listeners to find it when searching for the perfect song to fit an occasion.

Playlists that use data from Sonic Style feel like they were made by a person with a deep knowledge of music rather than a machine. That's thanks to the system's advanced neural network. It also recognizes artists that don't fit neatly into one genre, or that have evolved into a completely different music style over their careers. Any service—including music-streaming platforms and voice-activated assistants—that uses Gracenote's data will be able to take advantage of the new technology.

With AI at your disposal, all you have to do as the listener is decide on a style of music. Here are some ideas to get you started if you want a playlist for productivity.
