Fans of Big Sean and Future have been waiting to hear a particular collaboration between the two since 2015, and now the long-awaited track has finally surfaced online in full. Initially teased when Sean announced his project with Metro Boomin, Double Or Nothing, the Future-featuring "Know About Me" has made its way out.

As pointed out by HipHop-N-More, the Metro Boomin-produced beat for "Know About Me" eventually made its way out as Young Thug and Rich Homie Quan's "Color Purple." It's unclear if the usage of the beat on that song had anything to do with "Know About Me" not coming out officially, but it certainly might explain why we're only just hearing it thanks to a leak.

Earlier this year, Big Sean postponed his tour to work on his next full-length release, but "Know About Me" is unlikely to appear on it. He hasn't given his fans any indication on when he'll be putting out anything new, but his eagerness to work on the project speaks volumes.

Meanwhile, a solo Future track has also popped up online. "Take You Back" sees the Atlanta rapper going in a more pop-oriented club direction, ditching the grimy sound found on the recently released BEASTMODE 2. If this is a hint at what's to come from the mixtape's follow-up, he's definitely looking to take a different approach with the currently untitled album.

Future has remained tight-lipped on when to expect his next project, but knowing him, it won't be too long before we hear something more substantial from him considering his prolific nature.
