It's hard for foreign artists to have success on the States, and sometimes even American artist have problems with their albums' sales on the US. Recently with all the MJ stuff i saw an interview on TV where MJ was being asked about one album that sold millions around the world but didn't sell good in the US.

I can't remember which MJ's album.
Also ABBA is famous around the world but not so much in the States.

It's a weird phenomena.

Edit:

By the way i also don't like so much TITO but i looooooove Hikki's Japanese albums.
