Welcome to the Q&A Forum

Chris, You can focus on developing unique content around each product. You can provide "staff reviews" for each one, and encourage users to leave reviews to keep updating the page with new content. Also re-visit the content when any news about the CD comes up (say an artist wins a grammy for that CD) you can use that to build new content. If you provide great content like this people will share it and link to it. You mentioned you are building links, are you building links to these products also?
