I lost count in my Prince discography, but my best guess is that "Planet Earth" is his 32nd album. It includes some fine tracks and it's a superb album to start a Sunday morning. 'Too smooth', you say? 'Too much syrup', you add? Well, maybe you're right, but we're talking Sunday morning, so that's OK.
In the UK, "Planet Earth" was made available as a supplement to 'The Mail On Sunday', a British newspaper. My copy has this nice 3D cover. And it changes when you look at it from a different angle. Lenticular printing, as they say.
