It was only a few weeks ago that Slacker released their music player, and not to be outdone, along comes Pandora.  Fans of the service will be able to jump right in.  A quick install of the application and you're ready to rock (pun intended).  After logging in, the main menu gives you the option to create a new channel, start a "quickmix" or  play one of you created stations.  It takes a minute for the music to load, but that's to be expected (depending on your connection).  The main screen is slick - showing album art and info, as well as a cool status bar with signal strength and battery info.  Along the bottom are the thumbs up and thumbs down (when you like or don't like a track) as well as a play/pause button and skip. If you are a fan of Pandora like I am, you don't want to miss this.  Its totally free (ad supported) so you have no reason not to check it out.  Sadly it looks like it currently only supports Verizon and AT&T.  Just head to from your device to install.
