2) Redbook Ive seen this mentioned many times. what is it?
3) IMO. What does this acronym stand for?
4) Mendula Oblongada. Isnt that fun to say?

Medulla Oblongata is the lower part of the brain stem. Its main function is to connect brain and spinal cord, so be careful with it.

Actually the Medulla Oblongata controls many of the bodies automated processes as well as translates nerve messages from the spinal cord to the brain.

My Medulla Oblongata must be wasted and/or fried! I thought the discussion was about "Inna-Gadda-Da-Vida"...someone pass the bong this a' way, please!
I know how you feel, every day I come to this site, there's some word or acronym used that I don't know. I've been able to find the meanings of most of them through searches of past threads, that can sometimes take hours. Maybe Audiogon can create an audiophile dictionary? Or has one alredy be done here or somewhere else?
