Latin albums getting forgotten?

I notice that most of Spanish-language albums don't tend to be reviewed or rated, even by renowned artists in the Latin music market like Alejandra Guzmán, for example.

Moreover, I noticed, when looking at some of these Latin artists discographies, some albums are reviewed, others are not or many of their albums aren't even listed... Good example, Thalía: most of her discography is reviewed, however her last two studio albums are not.
