In Slacker Radio, curated stations that are organized by musical genre meet algorithmically-generated playlists based on artists you pick. As with Slacker Radio on other mobile platforms, the Android app lets you stream music from preprogrammed genres and stations, or from stations you set up yourself online. You'll be able to view album art and bios, block a song or vote it a favorite, and skip ahead--this is limited in the free version and limitless in the premium upgrade. If you like what you hear, you can share a link to that station on SlackerRadio.com via e-mail, SMS, or MMS.
Upgrading to the premium Radio Plus subscription service brings you song lyrics in addition to those unlimited skips and no ads. Version 2.0 adds the capability to cache stations for offline playback, so you'll have songs on standby to rock out to even if you're in a data or Wi-Fi dead zone. Caching comes as a free trial on the free version and is a permanent fixture in the Radio Plus subscription.
The widget, which you install by giving the home screen a long press and selecting Slacker Radio from the Widgets list, is embedded with pause, skip, favorite, and blocking controls.
