Question about cmi

Hi and thank in advance for any help :)

So a simple question, i saw a post in another thread (hematomas post) and this guys had out a link "[url]http://hematoma.net/"[/url] i saw in that link that when u press a letter from the "browse by artist link u get the artists and not all the albums from all artists in this letter.

When i put by artist in my cmi i get same thing but when i press lets say letter "a" i get all albums from all artists and not another page with only artists so i can click on the artist and get only his/her albums.

hope i make sense....
