I have the Pink Floyd one and it's pretty good, but has anyone ever tried these on actual kids?

The Rockabye Baby series of CDs takes the songs of popular artists across all genres and rearranges the tunes as lullabies. Keyboard approximations of celeste, vibraphone, chimes and other suitably dreamy instruments replace the original instrumentation, lending each song a music box-like quality. The atmosphere is light, ethereal and sleepy, never rising above background music levels -- perfectly in keeping with the goal of these discs. The Björk edition includes versions of "Human Behaviour," "Come to Me" and "The Modern Things." ~ J. Scott McClintock, All Music Guide
The bjork one also sounds like it'd give serious nightmares.

Punk rock parents with a hankering for offbeat nursery music might find what they're looking for in Rockabye Baby! Lullaby Renditions of the Ramones. An ethereal chorus of glockenspiels, toy pianos, sleigh bells, and synthesizers interpret songs like "I Wanna Be Sedated," "Pinhead," and "Teenage Lobotomy" to good (and at times hilarious) effect. There's nothing revelatory or particularly interesting about these renditions, but they do manage to unearth some surprisingly melodic elements of the Ramones' otherwise brash and stompy music. Other songs on this collection include "We're a Happy Family" and, yes, "Beat on the Brat." Margaret Reges
