My apologies if this has been suggested before, I didn't find anything when I searched so I assume it hasn't.

Basically, my suggestion is either one of two things: Artist pages autoload whenever you make it to the bottom, dynamically adding the items that would normally be on the next page without having to actually go to the next page; or, just give us the ability to display more items at a time.

We will consider the possibility of autoload tabs on the artist page, thanks for your feedback!
