Pithos is a Pandora client for the GNOME Desktop. The official Flash-based client is a CPU hog, and Pianobar is command-line only. Neither integrate with the desktop very well, missing things like media key support and song notifications.

Hermes vs Radia opinions
It takes very little memory, allows you to select the quality, skips ads, allows you to like, dislike, build and change stations, everything you can do with Pandora. And it is open source.
Pandorita is a native Mac OS X client for the internet radio service Pandora. It is written entirely in Cocoa, and built to be lightweight, easy to use, and fully functional. Internally it uses the amazing pianobar library to communicate with Pandora's server.
Pianopub is a free Pandora internet radio player for OS X. It is a port of Pianobar, so please support the original developers. It is for use with your account from the Pandora.com internet radio service.
