Tank shares the Wale-featuring "You Don't Know." We haven't heard form Tank in a good minute, but today, he returns with a track that should not only interest his fans, but also those of Wale. The track "You Don't Know" is taken from the R&B singer's upcoming album Sex, Love & Pain 2 (quite possibly the best three-word description of Tank's music), and features the Washington, DC rapper on a guest verse.
