OK,this is a new one for me, but now that I can carry a tune and have also been doing a telemarketing thing for a while now, I find that I can tell that I've dialed a wrong number, because it sounds off. I'm catching all the reversals that I used to make (646 for 464, for example) as soon as they're made instead of when I check... not that I can tell what tune a number will be, I've tried, but I *can* apparently tell if what I hear is not what I read.
Is this common?
