Slacker is another Internet radio service. It has apps for iPhone, Android, BlackBerry and Palm. Like Pandora, Slacker creates custom stations that play music of a certain type. But for a fee, Slacker also gives you unlimited access on demand to the music or artists you choose. If you want to take a break from music listening, there are also channels that offer comedy and news content. Slacker also lets you store stations and tracks temporarily to listen to when you're not connected.
Slacker lets you listen to more than 100 stations programmed by music experts -- a cool way to explore new genres. And Slacker can download lyrics for songs in case you want to sing along (or just figure out what the heck the words are).
