Question about Shazam

[Danja]

I downloaded the Shazam trial application with the 5 tag limit. I liked it a lot so I went back to the market and got the full version. I now have 2 Shazam applications; the first (in the order of my apps menu) still prompts me about whether I "want unlimited monthly tagging" while the second appears to be the full version with no prompts. I'd like to remove the demo from settings/manage apps I can't tell which is which! They have the same name and same icon. The only differences are version number and size; one is 1.70 MB and version 2.5.3-BB70303. The other is 1.89 MB and 2.5.3-BB70302. How can I tell which is which?
