iTMS album sales, notes

This post over at forbes.com talks about suggestions for iTunes, mentioning that some people (myself included) enjoy reading the liner notes from CDs - which you can't get from the online store currently. Here's a way to use that to increase album sales: give out the liner notes, but only with the purchase of a full album. You would still get the album cover when you buy a single though. I'm a jean-yus.
