Hard to define as they are many things to many people.
Yes, I found one copy of ANJ under "World" in the UK (in Piccadilly Circus, middle of London)....I told them they had better move them to "Top 50" and stock up in time for the UK Tour.
In Ireland I couldn't find them anywhere.
I have given up on WalMart.....I got sick and tired of searching among the 6 racks of "Latino" and "reggaeton".............I am definitely an ethnic minority at my local store!
I asked in Spanish too, but they had never heard of CW and looked at me as if I was doggie doo.
I did eventually find one of the first CD under "religioso"........
so I will only buy online now, no need to categorise and no need to stand in line.
