Do you think Congenital Amusia would fall under the Autism category, however mild it may be, just like Asperger’s? 

Isn’t it more like a type of agnosia?

Agnosia has to do with visual, not hearing

How does a lack of musical ability or tone deafness make a person Autistic. My friends son is Autistic and is extremely musically gifted in 30 second bursts at least. Socially he does not function well with strangers, but musically he is gifted. Autism is a mental condition, present from early childhood, characterized by great difficulty in communicating and forming relationships with other people it does not as far as I am aware make some one tone deaf.

No, it is a general term for any inability to process sensory inputs in a specific way - theWikipedia entry mentions hearing related forms (not recognising voices) and touch (not being able to recognise an object from what it feels like) and so on.
