Wiz Khalifa and Curren$y are musically kindred spirits.

The close friends and frequent collaborators have similar laid-back audio vibes, and aren't shy when it comes to rhyming about a love of marijuana. Their latest jam continues that legacy.

"Weed Nap," which also features SAYITAINTTONE and was produced by ID Labs and Frank Dukes, will be featured on Mister Cap and Spitta's upcoming collab mixtape, #2009. And from the sounds of this joint, they're channeling some '09 vibes -- which was the year they dropped their How Fly project. A few years later, in 2013, they released their Live in Concert EP.

In addition to the full projects, they've joined up on songs for albums, like "Scaling the Building" and "Rooftops."

These dudes bring the best out of one another, and clearly their musical chemistry is as intact as ever.
