When you purchase music from iTunes or many other digital music stores, you receive a highly-compressed mp3 file that’s a lower quality recording than you would get from a CD. HDtracks is a new site that sells only CD quality digital downloads, all of which are DRM-free (so they can be played on any machine) and come with a PDF file of the full liner notes and cover art. The albums available on HDtracks are all from independent labels, so you will not find many big names here, though Norah Jones, Nina Simone, Joan Baez, Tony Bennett, and Shania Twain are among those artists offered on the site. When you purchase music at HDtracks.com, you can choose from three file formats: AIFF, FLAC, or 320 kbps mp3. Because HDtracks are of better quality than iTunes, downloads are more expensive: complete albums cost $11.98, and individual songs go for $1.49. Both Mac and PC users can access this site, though it is currently available only in the U.S.
