Last year at IFA, we had a chance to check out a beta version of Gracenote's MoodGrid, an Android tablet app that automatically creates a music playlist using a 10x10 grid with Positive, Energentic, Calm and Dark criteria placed on each axis. Select a place on the graph and it automatically creates a playlist based on your mood. Now, the app has been scaled down and ported into a Garmin head unit, which means MoodGrid could be coming to a major OEM as soon as sometime this year.
After a particularly rough day, few things are more cathartic than getting in your car and reveling in some choice tunes to suit your mood. Sure, you could dial up one of the 'heads (Radiohead, Portishead, The Talking Heads...) and wallow in self-pity on your way home, or – if Gracenote has its way – you can simply pick your mindset and let the algorithm do the work.
If your vehicle or smartphone has voice-to-text functionality, there's a good chance Nuance is working behind the scenes. If you haven't checked out the company's iPhone or Android app, it's worth the download just to get a feel for the technology, and the company's next implementation is set to arrive in vehicles next year.
