But why do I have to click two times to see the newest band. First there is the order by number of fans. When I click a first time, it's sorted from the oldest added (Nightwish) to the newest.

The default sorting is by the number of fans. Only when you click on "Latest Band Additions" on the front page does it sort by date. And in that case, the order is correct (sorted from newest to oldest).

Yes but when someone is clicking on "last added", it means he has the attention to see which bands were last added, which makes sense given that it is marked "last added" and not "first added".

Depends where you're coming from. For the occasional visitor it's totally irrelevant when which band was added.

@Starvynth I know I'm talking about the functionality itself.

Wouldn't it be more logical to put the last added bands directly instead of having to click twice? I find this counter-intuitive and in my opinion users will watch newly added bands more often than older ones.

Just klick the button again.
