Pandora is a waste of time on the tablet. There is a far better option:
1. Install and run Kmplayer (requires mplayer)
2. Go to menu: Generators: LastFM Flash Player
3. Enter an artist name and enjoy continuous music from similar artists without having to suffer through loading Pandora into your tablet.

Advantages:
* There is no registration required.
* Loads instantly and painlessly.
* It is so light on resources that you hardly notice it running.
