While this kind of skill is nice to have, there is a curse to this kind of musical ability. I often find myself humming songs or fragments that I cannot place. Worse you cant just hum or whistle the tune into some app and have it tell you the song. And it's maddening when you know you don't have it quite right.
For example, for years I had a reoccurring little tune stuck in my head. I had nothing to go on other than a couple of bars of the song that repeated. One day I finally(!) figured it out when I got out an old copy of NES Mega Man, and selected Cutmans stage. The cutman theme had been stuck in my head for years, and it was quite the relief to know what the song was.
