It was a typo meant to be "worth noting". Many people have bandied about Apple's "higher rate" than Spotify, but the difference is likely to be only one hundredth of a cent per stream. Apple will pay out 71.5% of their $9.99 fee vs the 70% that Spotify does. An extra $0.15 a month per subscriber divided by all streams works out to about one hundredth of a cent per stream difference. So, a popular artist's paycheck for millions of plays of their song would be $10,200 vs $10,000 using the typical average streaming payout of a little over 1/2 a cent per play.
Plus, there's the fact that Apple Music will cannibalize a lot more iTunes sales than Spotify does.
