Burying in the search rankings and not being featured doesn't seem like a good way to handle it. If those artists are among people's favorites if they can't find them as easily on Spotify AND if they can get exclusives with Apple, why wouldn't they just jump ship to Apple Music?
Obviously I don't understand all of the nuances of the music business so I could be completely off base here but it feels like, to me, this would have the opposite affect that they intend.
