What You Hear Is What You Get
Like I said, listening to Pandora is kind of like listening to traditional radio, in that you have no overt control over what track plays next, but with a much more personalized approach. And just like radio, you can't rewind or repeat a given track; you have to listen to songs in their entirety and in the order presented.
That said, if you don't like a given track, you can give it a thumbs-down or skip it completely. Pandora lets you skip six tracks per hour per station, or up to 24 total skips a day across all stations. Use up your limited number of skips and you have to listen to everything they give youalthough you can still give a track a thumbs down for future listening.
As to what kind of music is available, the answer is "lots." Pandora offers up more than one million tracks in a multitude of musical genres.
Although there are services with larger music libraries, Pandora's capability to accurately target a listener's musical tastes have resulted in the service attaining a 70 percent share of the Internet radio market.
