System of a Down is the latest band to receive the 'Twinkle Twinkle Little Rock Star' treatment. Twelve of the Armenian-American experimental metal band's biggest tracks have been transformed into children's lullabies. 

Twinkle Twinkle Little Rock Star has released over 135 albums of re-imagined songs in every genre from pop to country to metal. In the heaviest genre covered by TTLRS, bands such as Slayer, Metallica, Pantera, Slipknot, Tool, Iron Maiden and many more metal acts have acted as the inspiration to introduce your little ones to great music.

The System of a Down version of TTLRS includes songs such as 'Psycho,' which covers the topics of cocaine and groupies; 'Chop Suey!' which details domestic abuse and suicide and 'Cigaro,' which hones the lyrics, "My c-ck is much bigger than yours" and "My s--t stinks right down through the floor." Luckily for unknowing parents, Twinkle Twinkle Little Rock Star's releases are simply instrumental sonic adaptations.

"These aren’t novelty recordings," begins a TTLRS manifesto. "They are cute, they are soft but these are serious recordings.  Roma Music Group, which releases Twinkle Twinkle Little Rock Star, is run by two music industry veterans who put the fidelity of these recording at the top of the priority list.  Let’s face it, much like the brand name clothes you buy for your infant, this music is really for you.  Whether you are raising a metal baby, rocker or hippie baby, Twinkle Twinkle Little Rock Star has your music transformed from arena anthems into nursery classics."
