Britney Spears will release her 8th album on Dec 3; "Britney Jean" is her first album since 2011, and it's likely to provide some of the material for her upcoming 2-year Vegas residency. In celebration, Slacker’s created a station counting down Britney’s biggest songs of all time, as determined by you, the Slacker listener. It’s something we call E.Q., the Engagement Quotient. That just means that these are your most hearted, least banned and most shared tracks. By the way, single-artist stations like these are usually reserved for our premium users, but thanks to a special agreement, everyone can listen to this one for a limited time. The Britney Spears E.Q. Top 33 -- something that could only happen on Slacker.
