I like when the booklet is written in native language instead of English. Since, besides ambient I listen to a lot of metal, I have a lot of CDs whose booklets are written in Swedish, Norvegian, Finnish or Russian, and even if I don't understanf a word, I like it. It's something different than the usual English standard booklet.
The same goes for the song lyrics.
