Nirvana, Sublime, Led Zeppelin, Nickelback, and even Metallica are just a few of the bands that 'Twinkle Twinkle Little Rock Star' have taken songs from and rerecorded into lullabies. Now Slayer has joined the ranks.

I mean, it's never to early to start molding your own little rock star by treating him or her to some metal. Sometimes it may be hard for a kid to sleep through Tom Araya's vocals or Kerry King's wicked solos. So instead, you can turn on these toned down lullaby versions and let your child drift off into a rock 'n roll dreamland.
