"More than Friends" is a song recorded by American singer-songwriter Jason Mraz featuring American singer-songwriter Meghan Trainor from his sixth studio album Know. (2018). It was written by Mraz, Trainor, Jonathan Green and Andrew Wells, and produced by the latter. Atlantic Records released it on October 8, 2018, as the fourth single from the album. A "bubbly" and "quirky" acoustic love song, “More than Friends” is about a pair of friends interested in taking their relationship to the next level, with implications of a summer romance. Darren Doane directed the music video for "More than Friends". Released on September 17, 2018, the video features a meta concept where a pair of co-workers at a video shoot admit romantic feelings for each other. This is interspersed with scenes of the singers performing the song. It was also supported by a dance video directed by Ryan Hutchins. Commercially, "More than Friends" charted at number 49 on the Belgium Ultratip chart and number 32 on the US Adult Top 40. Mraz and Trainor performed the song on The Ellen DeGeneres Show. Background and composition Andrew Wells produced “More than Friends” and co-wrote it with Jason Mraz, Meghan Trainor and Jonathan Green. After Mraz initially finished his album Know., Wells suggested that he have a songwriting session with Trainor. Mraz agreed to this, but was unsure of what would come of it. "More than Friends" was written during this session, and led to him pushing back "a few departments and their deadlines" to accommodate it on the record. With the song, Trainor intended to create her own version of Mraz and Colbie Caillat's song "Lucky" (2009). It was inspired by a conversation Mraz had with his wife, he said "My wife, she has these cute things she does, when I make her a cup of coffee, I'll be like, 'Is it good?' And she'll say, 'Oh, more than friends.' I thought that was so cute." "More than Friends" is a "bubbly" and "quirky" acoustic love song. It is sung in a back-and-forth style with Mraz opening with "It feels like we've been friends forever and we always see eye-to-eye", and Trainor responds "At the risk of sounding foolish/ I don't wanna fool around no more/ So if we're gonna do this, then let's do this/ You could fix my broken heart if it's all yours." It has a "catchy" chorus and "summery, carefree vibes."
