Spotify grows by 0.6 m paying subscribers per month, so at the current rates, it'll take about 3 years for Apple Music to overtake Spotify (when they'll both have around 50m paying subscribers).
It's nice that Apple Music will have lyrics starting this fall, but they aren't time synced like on Spotify Desktop (where it lights up each line as it plays - plus you can scrub the lyrics, so you can have it jump to a specific verse or the chorus or something if you want.) Spotify needs to hurry up and get that feature on mobile... I don't understand why they haven't done that yet.
Also, more important than Spotify's losses growing by 10% y/y is that revenue is up 80% while spending is only up 70%. If they maintain that growth rate next year, their losses should shrink by around 50% for this year, and they'll be profitable next year.
