So far, I like most of iOS 10, haven't played with it much since I updated right before I went to bed last night. But, I do not like the Music app at all and am reconsidering my Apple Music subscription because of it if I'm not going to use the app. And because of the way that I use my phone, I changed the lock setting so that once the phone is awake (from the raise to wake feature) all I have to do is put my finger on the home button and touch ID automatically unlocks it (without having to press the home button first). It may seem trivial but it was bugging me.
