Apple will make big changes in Apple Music at WWDC
iOS 10 will be introduced in the WorldWide Developer Congress, and it looks like iOS 10 will come with an updated Apple Music.
First change would be the design. Rumors indicates that Apple will use a new user interface Apple Music that is based on black and white. Right now, Apple Music is colorful, but it looks like Apple is not happy with the current version. Anyway, the second change would be the 3D-Touch previews within the app. That will probably allow you to preview your playlists.
