McCartney, West, and Rihanna: the most successful synthesis of three musicians who I'm not particularly crazy about. The composition to my ears is the weakest of the 3, however. 80

Cave and Minogue: I like Cave but I don't know his material very well; I'm not a fan of Minogue. Still, the tension between the two artists / styles makes this one work. 85

Queen and 5ive: I'm not a Queen fan, but their participation here is the only thing interesting. I don't think 5ive adds to (nor do they subtract from) the equation. 79

My own suggestion for an unusual combo: Mike Heron (Incredible String Band), Pete Townsend, John Entwistle, Keith Moon (from you know who) and John Cale, "Warm Heart Pastry": https://youtu.be/QHoqssrKBFg
