PanTunes 3.0 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X was originally designed by MacFanr. The application lies within Audio & Video Tools, more precisely Players. We recommend checking the downloaded files with any free antivirus.
From the developer:
PanTunes is a native OSX client for the Pandora Radio music service. It’s much more lightweight than the Pandora.com web client, and integrates with desktop features such as media keys, notifications, and the status menu. This app implements most of the useful functionality found in the Pandora radio web player. The current version now includes the ability to play, skip, save and rate songs.
