Smule has released an update to its Glee application for the iPhone, iPod touch and iPad. Updated for Season 2 of the popular TV series, Glee Karaoke introduces a global competition mode where users sing to compete with fellow Glee fans from around the world and complete individual singing missions to gain levels and win starburst points and gleeks. Glee Karaoke also provides personal voice coaching tips to improve singing skills as well as pitch correction and three-part harmonies as fans sing along to their favorite songs from the TV series. The app includes the songs Rehab, Somebody to Love and You Keep Me Hanging On with additional songs available via in-app purchase for $1 each including such favorites as Hello, Somewhere Over The Rainbow, Can’t Fight This Feeling, Imagine, Defying Gravity, Jessie’s Girl and more. Users can also get free songs by earning Gleeks through sharing their top songs with friends on Facebook, MySpace, Twitter or Smule’s own Sonic Network. Additional new songs are added each week that an original episode airs. Glee Karaoke 2.0 is a universal app available from the App Store for $1 and is a free update for users of the previous Glee app.
