This Christmas we launched a 12 Days of Christmas Sweepstakes for Interscope artist Gwen Stefani at http://www.tweematic.com/gwenstefani/. Each day for 12 days fans were able to activate with Gwen on a variety of music and social media platforms including Spotify, Twitter and Facebook.  Fans were able to connect with Gwen on Spotify, for example, follow her plus add her music to their playlist and be entered for a chance to win great daily prizes.
