Over at Daring Fireball, John Draper consults his magic 8 ball on why Napster won’t dent the iTunes Music Store.

My question: 10,000 songs is just under 42 days of non-repeating music, at 12 hours per day. This would be a bit longer than a month. So does anyone really think of “filling my iPod monthly” as a selling point? Most of what you go through the trouble to select and download, you’re never going to actually get to.

But my entire music library would fit easily on an iPod shuffle, so maybe I’m not the guy to ask.
