To answer the question upthread, there is no Shopping Cart in vers 9. You can place items in a wish list, but that's not quite the same as being able to select a bunch of tunes then see what the total will be before you start downloading.
Never got a password prompt, nothing. Not even a "You have selected X. Do you want to continue?" Apple probably needs to brace for a bunch of consumer complaints. The FTC will not be pleased.
