How Did You Know? - {day 1}

Play for your chance to WIN a $100 shopping spree in our store!

We're back with another 5-day trivia hunt!

First let's meet our current champion, and big $100 winner, Daniel Wilson. You can read all about him and see the answers to last month's final puzzle here.

As comments have been turned off for the length of the 5-day hunt, be sure to hit us up via e-mail with questions if you find something in the instructions unclear.

As always, it pays to play whether you're the first in with all the correct answers or not. In addition to the $100 shopping spree first-prize, we're also giving away a $50 shopping spree in our store to one random winner who has all the right answers but isn't the first to e-mail them in. Random winners sometimes submit all the correct answers/logic a full 48 hours after the closing bell, so don't worry if you're late or can't submit your final answers at 8 pm ET next Monday.

Have fun with it, and, as always, don't hesitate to work in teams and e-mail all your friends for help. Many, if not most of our past HDYK winners have been teams, not individuals.

If you're new to the 5-day trivia hunt, be sure to see the rules and regulations page here. Also, we've now got a Facebook page which we're going to use to drop cryptic clues now and then. Don't worry, even if you're not a Fan of our Facebook page, you can still view it through the link below, and, of course, you'll still be able to solve all the puzzles, as normal, even if you don't want to visit Facebook. But the Fan page will allow you to friend other contestants, form alliances, network and just hang out with other trivia nuts. So go check it out over here. Now on to our first challenge!

We're going to start you off on the easy side today with a two-part challenge. Solve each part of the challenge and hold onto your answers until next week. Ready to play? Click on through to the challenge.

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.
