If you've ever listened to CDs or digital music on a car or the computer, you've already encountered Gracenote -- even if this is the first time you've heard of the name. Gracenote recognizes tracks as they're played and displays the title, artist, and (for newer auto infotainment systems) even the album art. Now Gracenote has launched a brand new product for in-dash systems called "Entourage," which is a completely different entity from the company's Automatic Content Recognition System for TV with the same name. Entourage for cars was developed to augment your streaming and internet radio apps -- it's not an app itself, but rather a technology that infotainment systems can use. A company spokesperson gave this scenario to GigaOM as an example: when you hear a particular song playing on FM radio, you can tell your car's dashboard loaded with Entourage to create playlists across all your apps, or even in just one of them, like Pandora.
