Is that a big of a deal she's in on free period or not? Apple Music will match any songs you have in the library even a crappy 96 kbps mp3 to 256 AAC. You can get "1989" in your library in no time, and with a good quality no less. This will pose no problem for anyone who intend to stay beyond a free trial, just saying'. :)
Yes, Beat 1 will be accessible free of charge on the countries that Apple Music launches (supposedly +100 ones) You did. It's 3. :D You can like and dislike a song to let the algorithm know your taste.
Free Spotify is for people who's not interested in paying for music, poor quality and only shuffle, something Apple want to remedy with Apple Music. Getting music value back is one of the point in the keynote. I understand that it will be hard for some indie labels on the free trial period but they did it to themselves when they allow Spotify to stream their songs for free.
