Because the internet is on-demand, and iTunes is all about instant gratification, why not offer free 30 second previews of songs, before the CD with those songs are released.
Pre-release previews of songs would be a good way to build momentum for an album before it's actual release, and it might make some people load up their shopping carts with music that is yet to be released.
•Pre-release previews of albums and songs
•More album art (inside cover-art with lyrics -- obviously limited to more popular music)
•The option to download higher bit rates of music
•The eventual lowering of prices for 128 AAC to 79¢ per track
•Higher bit rate AAC for 99¢ and above
