I currently use iOS 9 on an iPhone SE. I frequently use the Music app to play a specific playlist of relaxing music before bed, so I like that from opening the Music app the playlists list is easily accessible. (The playlists tab is always on the bottom, unless a song is playing in which case I must minimize that first). And I can often bring up that particular playlist in the app so later when I go to the Music app it's right there for me to tap the first song.
My concern is with the Music redesign in iOS 10, which I have not personally used and is part of my reason to be hesitant about upgrading. My question is, how easy is it to access playlists (and other parts of the app, like artists or songs), and is it easy to open a playlist so it will be there for me next time I open the app?
