Really, it's not any better than American pop. It gets just as overplayed, it's just as overplayed, etc.
I wouldn't pay attention to all of these kids screaming AMERICA SUXXX JAP SUPERIOR BEAUTIFUL WOMEN ANIME ANIME ANIME
Most kids who listen to Jpop are the same kids who get excited when they see a Japanese person, or use the word "Hai!!! or "Arigato!" and use Japanese names as screen names.
