This update, and the concept of the Liked Songs playlist is a mess. The most basic feature in any music player - shuffle all songs - seems to be impossible now. The concept of simply saving songs to your library? Out the window.  

The way things are set up now, what once was a unified library has been split into two: 

1. Songs you've been saving and adding to your library for years are now just songs you've "liked", and shoved into a playlist (with no way of filtering by Arist or Album - try using a 6000 song playlist without these, it's not fun)
2. Full albums you've been saving to your library are still there, but they're completely seperated from the individual songs you've been saving which are now hiding in that playlist

Also don't get me started on the destruction of the Artist page. Instead of simply being a list of Artists in my library, it's now a list of artists I "follow"? And we have to manually go through and follow every single artist we listen to? 

What problem is this update solving? What was broken about the library system that needed these changes? I don't think you're ready for the general public's reaction to this update... I have a feeling it's not going to be pretty.
