Definitely better than before. Goes more in line with ICS/Jelly Bean app design guidelines IMO.
What's in this version:
* All new look with improved navigation and design updates
* Song history - review, rate, or bookmark previously played tracks
* Explore the music you love with:
full song lyrics
similar artists and tracks
and track features from the Music Genome Project
* Additional bug fixes and enhancements
I was really excited when I saw the changelog this morning. Pandora app UI was sorely in need of an update. I haven't had a chance to fire it up yet ... been too busy at work. But I'm definitely gonna check it out this afternoon.
