In the time since Avicii‘s passing, fans have scoured the web for new music the producer might’ve been working on before his death at the end of April.

Avicii fans have uncovered an unreleased collaboration between the producer and Chris Martin: “Heaven.” The two powerhouses were seen working together and were featured in a scene in Avicii’s documentary, “True Stories.”

The song’s cheery vibe is bittersweet in the wake of Avicii’s passing, featuring a lighthearted melody and emotive vocals from the Coldplay singer.

The SoundCloud user who uploaded the song says he found it on an Avicii Reddit page.
