It has been a couple of months since we last mentioned Sleeve Music. This app is currently exclusive to Windows Phone 8 and will be available on Android and iOS later this fall. Version 2.0 is out now, introducing a new look with a light theme. Sleeve Music lets you track and discover your favorite artists by grabbing content from Soundcloud, YouTube, Facebook, Twitter, and more.Sleeve Music isn’t another type of Pandora or Spotify service. If you want to start listening to music right away, this isn’t the app for you.It’s geared towards keeping you up to date with the artists you love. This app is only useful when you have artists in the list.
