Keith Richards wearing white headphones would be like Josh Groban wearing a skirt.
Or Steven Tyler wearing men's clothing.
Somehow, it wouldn't seem right.
Fortunately, it is unlikely to happen, because the Rolling Stone who once fell out of a tree has revealed he doesn't own an iPod.
Indeed, as the Associated Press reports, Richards believes that Apple's song-storing machine shortchanges those who truly love music.
The ribald and rollingly drunk will suggest that, after so many years of playing noisy music and ingesting uplifting substances, it's astonishing that Richards can hear at all.
However, he insisted that he is deeply committed to more vintage means of music listening.
The AP quotes him as saying: "I still use CDs or records actually. Sometimes cassettes. It has much better sound; a much better sound than digital."
Please pause for a moment. Keith Richards still listens to cassettes. That's as if you suddenly discovered Eric Schmidt still used a BlackBerry..
Richards insisted that he wasn't totally, completely, utterly anti-iPod.
He said: "My old lady's got one. My kids have got them. I say, 'Look me up this.' Or, 'Oh I like that. Check me that."
One might conclude, therefore, that the iPod is a useful product for those who serve as one's own personal reference library.
Digital is so often regarded as representing progress that it's easy to forget what might actually be lost.
This doesn't bother younger generations so much. Many have never heard a CD in their lives. But at least they might know what one is.
But a cassette? Is that, like, you know, like, something you put your jewelry in?
