Slacker Radio is a free mobile application that allows listeners to create custom music stations; enjoy over a hundred Slacker genre, seasonal and spotlight stations; and listen to over ten thousand artist stations.
Slacker also provides artist biographies, album reviews, station fine tuning, peek ahead song previews and song lyrics. In addition to marking songs as favorites, listeners can also ban songs and artists to create perfect custom radio stations on their phones.
On November 6, 2009, Slacker announced that the Slacker Radio app is available for Android phones.
