Press release from Apple:

Apple today announced that its revolutionary iTunes® Music Store sold over one million songs during its first week. Over half of the songs were purchased as albums, dispelling concerns that selling music on a per-track basis will destroy album sales. In addition, over half of the 200,000 songs offered on the iTunes Music Store were purchased at least once, demonstrating the breadth of musical tastes served by Apple's groundbreaking online store. Apple also reported that over one million copies of iTunes 4 have been downloaded, and that it has received orders for over 110,000 new third-generation iPods since their introduction a week ago, with music lovers snapping up more than 20,000 of them from stores in the U.S. this weekend.

....Apple also announced that tomorrow, May 6, the iTunes Music Store will be adding over 3,200 new tracks, including major new album releases such as Jack Johnson's "On and On," Andrea Bocelli's "Tosca" and Fleetwood Mac's "Say You Will," as well as pre-release tracks from upcoming albums by artists David Sanborn, The RH Factor, John Scofield, Jesse Harris and Lizz Wright. Also to be added tomorrow are additional albums from the Eagles, Michelle Branch's album "The Spirit Room," and new Featured Artist pages for Coldplay, including an exclusive track and music video, and Alanis Morissette, with her catalog of music.
