Songs from In This Moment are meant to rock, not rock-a-bye baby. Tracks like "Whore" and "Sex Metal Barbie" aren't exactly baby friendly, at least not in their original forms. But that hasn't stopped Twinkle Twinkle Little Rock Star from choosing In This Moment as the latest band to have their music transformed into instrumental lullabies with the album Lullaby Versions of In This Moment. Check out the lullaby version of "Beautiful Tragedy" above.

In addition to the aforementioned tracks, the other In This Moment songs getting the lullaby treatment on the album are "Adrenalize," "The Promise," "Blood," "Big Bad Wolf" and "Sick Like Me." You can hear samples of the songs at Amazon.

There have been over 200 lullaby albums released by Twinkle Twinkle Little Rock Star using artists from many different genres. Some of the rock and metal artist albums include Avenged Sevenfold, Disturbed, Five Finger Death Punch, Iron Maiden, Judas Priest, Metallica, Megadeth, Motorhead, Pantera, Slayer and Slipknot.

You can see In This Moment perform non-lullaby versions of their songs when they hit the road on a tour with Five Finger Death Punch and Papa Roach that kicks off Sept. 4 in Lexington, Ky. Speaking of Papa Roach, In This Moment's Maria Brink appeared on the song "Gravity" from their latest album F.E.A.R.
