You can listen to albums before they're released on Pandora.

Pandora Radio (http://www.pandora.com) is a nice music streaming site and app for listening music to enjoy your time and your own world. Example: I am listening Taylor Swift's 22 and writing this post. LOL, back to the topic.
Have you ever want to listen to an Album before pay for it? Most people will say YES. Now, Pandora allows listeners to preview upcoming albums up to a week before their release. That's a great function, isn't it?

The company said it will feature previews from a wide variety of artists, both established and emerging and across multiple genres.
Pandora Premieres will be updated weekly with new releases. Users can choose to hear any track on a featured album, in any order, and as many times as they'd like, for the time period the album is available on the station. Some artists also will offer additional exclusive content such as video interviews.
The albums debuting Tuesday include artists from the classic rock and folk music genres, including John Fogerty's "Wrote a Song for Everyone" and Laura Marling's "Once I Was an Eagle."
While Pandora said Premieres will include established artists, it's unclear whether any of them will have the buzz of Kanye West or other top performers. A Pandora spokesman told that "we cannot comment on future artists but are ensuring that we are covering a wide range of genres and showcasing both established and emerging artists, true to Pandora's spirit of discovery."
