Slacker has released an updated version of the Slacker Radio app for Google Android. The key change is support for higher bit rate audio files and larger album art when you’re connected to a 4G network.
There are also a number of bug fixes, and Slacker 2.x includes a free trial of offline station caching, allowing you to cache music to play when you’re offline.
Slacker Radio is available as a free download from the Android Market. To continue using the offline caching after the trial is up, you’ll need to sign up for a Premium account which costs $3.99 per month. Slacker’s basic service is supported by advertising, but Premium subscribers also get to skip the ads.
