I like d-minor. Nice easy key to play in, makes minor key music sound majestic.
I can tell an augmented chord from a mile away. (Augmented is stacked two major thirds instead of a major and minor.) I have synaesthesia, which means sometimes my senses cross over. Augmented chords make me see red (an impression of red, not as if my whole vision goes red, and not as if it makes me angry.) I never missed an augmented chord on a listening exam.
