Amazon-backed streaming music service Songza Media has introduced a new Music Concierge feature in an update to its free app for the iPhone and iPod touch. Songza is a free social streaming music app featuring a large collection of curated playlists organized for a wide variety of moods, genres, eras and cultural themes. The new Music Concierge service is designed to allow users to find and listen to music for specific situations based on time of day, day of week, current device and observed past preferences. With two simple taps, the app will recommend up to three playlists from the Songza collection designed to accompany the user’s current activity or mood. A different day and time can also be specified to provide an alternative playlist selection, such as pretending it’s late Friday night instead of early Monday morning. As before, users can also explore Songza’s entirely library of expertly-curated playlists to specific themes or tracks, and add playlists to their favourites for later listening. The application is completely free with no advertising or listening limits and users can also collect and share their favourite playlists via Facebook, Twitter or e-mail. Songza 1.3 requires iOS 4.1 or later and is available from the U.S. App Store as a free download.
