Nothing like some nostalgic weed smoking to bring together a 20-year-old pop starlet from Nashville and a 41-year-old West Coast gangster rapper-turned-reggae mon! If that's your thing, you're luck: Miley Cyrus and Snoop Lion have teamed up for "Ashtrays and Heartbreaks," a song off the Lion's upcoming album, "Reincarnated."

It's a generally inoffensive tune that features both vocalists offering breathy reflections on lost loved ones. Some might accuse Snoop Lion of a certain inauthenticity, but let's be honest, if there are two people who are going to sing about pot, these aren't the worst choices.

If working on a reggae-lite album seems like a surprising move for Cyrus, consider the fact that she last made music headlines by appearing in a raunchy video for Borgore's dubstep song "Decision." She's nimble in this industry!

Snoop has stayed busy doing press runs for the movie and album. In an interview with HuffPost, he said "Young, Wild and Free" would make a nice new national anthem for the United States and backed same-sex marriage. "People can do what they want and as they please," he said. "Satisfy yourself accordingly. I have no issues with nobody, I live for me and I live my life doing what I do, so you should have the right to do whatever you want to do."

Diplo debuted the track on Major Lazer's SoundCloud page. Major Lazer produced the record in Jamaica, where Snoop filmed a documentary about his personal renaissance, also called "Reincarnated." The movie is a VICE project. Diplo took a hardline on the NRA in a recent tweet endorsing "No Guns Allowed," another "Reincarnated" song that features Drake and Snoop's daughter. The "No Guns Allowed" video debuted earlier this week.
