Real Super Powers

You guys know how there are the Psychokinetics, whom can influence mattter on any level with their minds, then there are Psychics, who are able to use the mental abilities to an advanced level, such as precognition, esp, then there are the Metahumans, who are people with physically-based abilities, and now I would like to add another category. The Singers. These people don't exactly have physically based abilities, though they can have them, nor do they have to have psychic or psychokinetic tendencies or abilities, although they can. Their abilities lie in the power of energetic resonance. Now this resonance is usually with a very specific type of energy. This can include lost objects, certain animals, certain humans with specific physical, mental, or emotional traits, even computers. My Resonance are blades and objects that could e used in a blade-like fashion. Just a thought.
