The list's compilers aren't specifically identified ("our editors") and their criteria remain shrouded in mystery. So I'll offer my own criteria, if not my own top 100 list (at least, not today). The best global albums of all time should first of all be ones that you turn to again and again. They should have some global impact, perhaps spawning imitators and spreading certain rhythms. And they should have clear roots in their local culture, have a message that's rooted in that culture but is also universal. Finally, they should simply hit you where it counts.
Finally, if you have a list of 100 of the greatest world music albums of all time, you want to have a sense of history. It's easy enough to include such talented newcomers as Sara Tavares, Rodrigo y Gabriela, Think of One, and Konono No. 1. But only the shortsighted editor would fail to include seminal artists such as Miriam Makeba, Zap Mama, Tarika, Vusi Mahlasela, The Mohatella Queens. And while I'm on a roll, also missing are Johnny Clegg, Lila Downs, Dorothy Masuka, Virginia Rodrigues, Susheela Raman, Vera Bila, and Fanfare Ciocarlia -- artists I'd likely rank above the likes of Solomon Ilori, Willie Bobo, and Ami Koita.
Still, the Amazon list is a great starting point for delving deeper into global music, so kudos to them for compiling even a flawed effort.
