Originaltext - Malaiisch - Dapatku membayangkan Dari senyum bibirmu itu...

This is not japanese ...

its portuguese i guess, i check it from some online translation site and most similar translation matched to portugese.

it can be spanish too..

I does not look like portugues, I guess milena would have seen it

OK, I googled a bit and this is part of the lyrics of a song by a Malaysian singer
Artist: Anuar Zain
Song title: Sesucinya Cintamu

The language is Malaysian and I found a translation of the song in English although obviously I cannot vouch for it

IT's Indonesian/Malaysian
