Prior to the most recent update one could find the Charts for top songs and albums from all over the world in the sidebar near Browse and Radio and the like. From there it was easy to switch between countries without having to go back to a main charts page, let alone find the Charts. Frankly I'm not sure how I did at all, because upon leaving the Charts I could not find them again on the Browse page under any subheading.
This was very convenient for seeing what was coming up both in my home country and around the world. I found a lot of gems that way. And I see that the new Charts functionality on the update includes arrows indicating if something is going up or down which is great, but if its buried so deep I can't find it again it doesn't do me any good.
