Some of the changes include a blue and white color theme, larger album covers (more on the covers later) and with the reworked song history, you can review, rate or bookmark songs you've previously played. And the album covers can now be minimized to reveal artist bios, song lyrics, similar artists and songs, and the features of the track that put it on the play list of your personal radio station.
If you liked Pandora on Android before, you're really going to love it now. You can download the updated Pandora for free from the Google Play Store.
