The solution to the iTunes problem for display of music, as explained by somebody on another list is as follows.
If you vo space on the "albums" "pop up" which is just to the right of the itunes store radio button, you will then get access to some controls, including a table. Interact with that, and you will see different choices like songs artist etc. Vo space on artist, and that album grid will be replaced by a artists table, which you can navigate using first letter navigation. You can also select what columns you want in that table and how they are to be ordered, I believe, but I haven't tried all that yet. Mary
