How Did You Know? [Day 3]

If you're just joining us, every day this week, I'm presenting a specific challenge. Your job: come up with the answers and hold onto them! Why? Because on Friday, you'll need them to solve a short puzzle. The first person to email in the correct answers and successfully show how you arrived at them (thus the title: How Did You Know?) wins a choice of any t-shirt or book from our store.

As with our previous challenges, I definitely encourage you to work in teams. Email your friends, send around each daily challenge, conspire, work together, whatever it takes to make sure you're armed with the right answers going into Friday's puzzle.

In case you missed Day 1 of this feature, check out Monday's challenge here. Day 2 is right over here.

Today, we're playing "One of These Things is Not Like the Others," if you remember the Sesame Street game. Each of the three following videos and two article headlines have one not-so-obvious thing in common. However, all but one have TWO not-so-obvious things in common. Your job is to figure out which is not like the others and why.

Let's start with some Sesame Street then. Click through to each subsequent page for the others... though not necessarily "the others."

If you're still stuck, check out the last page for a hint.

Hint: They say a picture is worth a thousand words. However, for this challenge, a word is worth a lot more than a picture!

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.
