This was bought for me as a gift, but it is completely unneccesary. It's simply a case of a company using widely available technology to make some money off of peoples' ignorance... If I hear a song that I wonder "...hmm, what was that?" I simply log on to the StarCD website and choose the radio station I was listening to and the time. It uses the same data that this device does. The only thing this device does is record times. If you think its worth spending the money for a keychain timestamp-thingermajig, go ahead. Ill just jot it on my hand with a pen. (I have no commercial or otherwise affiliation with StarCD, I'm just an impressed user.)
Negative
