Although post-grunge has become one of the more widespread genres of the past couple of decades, its failure to take root in the baby demographic has baffled record company executives since time immemorial. Fortunately, Rockabye Baby!: Lullabye Renditions of Nickelback, is here to make it all better with gentle, instrumental arrangements of the Canadian band's emotive tunes designed to help your child sleep while still exposing them to some radio-friendly rock. Just the thing for any parent looking to add a little edginess to bedtime.
