Slacker Radio is a pretty good music streaming application. It has all the songs and artists you could hope for, and you have the option of customizing your stations. Occasionally when the screen locks due to inactivity, the application will freeze when I try to unlock the screen and needs to have a force close. Also, it is a bit annoying that even with the premium subscription there will be 3 second commercials, telling me that I am listening to Slacker Radio. Overall I love Slacker and hope that the app continues to approve.
