There are many valid reasons for that.  We tune to make the audio sound 
normal.  For me, if a station adjusts their audio to add 200 Hz on the 
low side, I will tune almost exactly 200 Hz high.  Two times recently 
the other station kept telling me I was 200 Hz high. I asked him to 
remove the 200 Hz he'd added to the lows and I was right on frequency.

He randomly turned the 200 Hz on and off and every time I shifted 
frequency.  So the problem is as much stations transmitting a non 
typical audio.

I had the same situation with one other.

We have all sorts of permitted modulation.  If they want to run AM for a 
bit of nostalgia, I have no problem with that.  I don't operate AM, but 
I don't demand they stop.

So they're a bit wider, but seldom wider than an over driven amp with 
poor IM.
