Apple Thoughts: Shazam Updated, Now With Restrictions

"Shazam Entertainment quietly updated to its popular free Shazam app last night to add support for looking up tour information for tagged artists."

If you downloaded a previous version and upgrade to this one, you get a bonus with the concert info. However, according to the documentation on iTunes, if you are a first time user and download this you will only get to tag 5 songs per month. People upgrading won't have the same limitation. I think I would have preferred they add enhancements to the paid version to make it more enticing than taking away functionality from the free version.
