With this new release, the app is being considered a premium program, meaning that you need to pay for it now. The free version of Shazam will still be useable and downloadable. However, new users of the free version are limited to five Tags per month.
This seems like a neat program, although I have yet to use it myself. It also helps in introducing people to new music and would lead to at least some increased sales. Apparently it features Twitter and Facebook integration of some sort, so I am sure that there is some additional marketing opportunity in that functionality.
