Whether or not eBooks should have soundtracks is controversial, at least among eBookNewser readers. But for those that like the idea, Cathedral Publishing, a company that makes multimedia publishing tools, has a new application available that lets authors sell songs from within an eBook.

The tool called “Book IS the Store,” is intended for self-published authors who also might be musicians. Authors can use the tool to embed songs into their eBook as a soundtrack and then sell the songs as MP3s through links within the store.

Cathedral Rock used this application in the company’s own self-published eBook called Cathedral of the Senses. Watch the above video to see how it works.
