i think it's a bit too late from apple to introduce music streaming. should have started long ago. now that everyone loves spotify, only hardcore apple fans will use it (yeah, I have one friend of mine who already in love with apple music and she's an apple fan). for me, i already stopped using itunes since last year because it was sluggish on my laptop. spotify does it's job really well without much RAM hogging or any lags (except when unifi being a b*tch of course).
