The eccentric rock star, who helped produce her 2015 project "Miley Cyrus & Her Dead Petz", thinks the pop star should follow his band's example and give fans a little extra - The Flaming Lips used beer and human blood to make one of their phonographic albums, and Coyne thinks Miley's next record should be pressed with a fluid from her body.
"You can't really up the ante too much from human blood...," Coyne tells the Daily Mirror. "We'd get a good amount of Miley's pee and mix it with some glitter and put that in. I think that would up the ante."
Meanwhile, Wayne insists Miley is always welcome to lay down tracks with him, because his wife is the pop star's best pal.
"The Wrecking Ball" singer teamed up with Coyne and his band for tracks on their 2017 album "Oczy Mlody", and though she might not be quite as 'out-there' as she was when she became a muse for the rocker, he is still keen to work with her again and he thinks it's inevitable they'll hit the studio together, because the pop star and his wife, Katy Weaver, are inseparable.
"Her best friend is my wife (and) there's a lot of time spent together," he tells the U.K. tabloid. "They can be gallivanting around town or whatever, and I could be in the studio getting something together. At the end of the night she could run in for an hour and we'd do two or three tracks. I loved that way of working, there was enthusiasm and joy involved."
"We are still great friends (and) I'm always making a record. I mean, I always have three or four things happening at the same time. I think she knew that. If we're going to be friends and hang out together, we're going to end up making a record. That's just what I do."
