Stuttering can be much more complex than just repeating a single letter. I grew up with a severe stutter - it still creeps up on me from time to time but has subsided considerably.

The single letter repetition can also occur in the middle of a sentence or, for that matter, in the middle of a word. Another common feature of stuttering is the total blockage of sound which can occur at the beginning or anywhere in the midst of a sentence or phrase. There are many other example of other kinds of stuttering but I'd better stop here because I feel my blood pressure rising just talking about it. The terms stuttering and stammering, in my experience, are interchangeable, at least they are in the States.

Unless you have had the problem yourself you really can't imagine what ridicule stutterers endure. Many people find it quite amusing and I hope that the reason for finding stuttering songs in this case is not one of humor.

My reaction to this subject is rather visceral due to personal experience so please excuse my ranting here.
