I'm fond of a song titled: "Josè embala o menino" ("Joseph Rocks the Baby"). I've heard it performed both by the Portuguese singer: Maria Ana Bobone as well as by the late Spanish vocalist Montserrat Figueras. And I love both versions. (They're both on YouTube, by the way.) And then, speaking of Montserrat Figueras ... she recorded an audio CD of lullabies from a number of countries, covering the period from 1500 to 2002, titled: "Ninna Nanna". Her performance of "Josè embala o menino" is on that CD. It's a favorite. Those probably aren't the sorts of things you had in mind. But they're favorites of mine.

P.S. These aren't nursery rhymes / songs, but if you happen to listen to "Ninna Nanna" & find it to be of interest, there's another audio CD Montserrat Figueras recorded titled "Lux Feminae" ("The Light of Women") that is wonderful too. It's also on YouTube.
