What is your favourite song that’s not in English?

I'm fond of the first Enigma album, especially cause Frank Peterson a.k.a Father Gregorian was involved in it, that's why it sounded a bit different than the other Enigma albums. He left Enigma right after that. Greogorian went on to have other musical projects that had similar musical themes he had brought into the Enigma project. You can hear his influence on some of Sarah Brightman's albums also. Try listening to So Sad by Gregorian in YouTube.
