We can safely say that the new update is much more intuitive and focuses on ease of use, compared to earlier versions of music- the swiping action makes it much more fun and easier to navigate through the UI. The other changes are a bit minor, including a new large album art view, a Now Playing widget that supports thumbs up and album art, among others.
The Playlist art is now created from the album art of the different songs on your playlist, while the Now Playing queue allows you to queue and reorder the music beng played currently. However, something that is a bit unwelcome is the fact that the “back” button present in the widget has now been replaced by a “thumbs up” button.
Overall, this is a pretty good update so go ahead and download the update today.
