I acutally don't know how this is done on the iOS Apps but at least for Android I'd like to see the Top Lists for Tracks with more than 20 Tracks (e.g. 100 like on PC). Additionally I would like to have Top Albums in the Android App.
If this is also not supported in the iOS Apps, I would say, this should also be implemented on that side.
