One of the most popular applications for iOS is Shazam, which allows us to identify songs just by 'listening' to them for a few seconds through the iDevice, but you may have wondered if you can do that on Mac OS X.
The answer is Tunatic. It works exactly like Shazam to tag songs with a catch: precision is not its strong suit and it seems that it is not very sensitive either, since it has made me play the music too loud.
I will continue to use the iPhone for these things, but if you want something for Mac, you already have it.
