Idea for Amazon regarding their MP3 store: allow people to pre-order MP3s and when they're available for download, send out an email to that effect. For instance, the new Sigur Ros album is out on June 24. A page for the MP3 album exists but it's difficult to find and while you can preview tracks, you can't pre-order the album.
