Rock your baby

LOS ANGELES -- If you know nothing about Metallica, "Enter Sandman" does sound like it could be the title of a lullaby.

A company called Baby Rock Records has created lullaby versions of songs by Metallica, Coldplay and Radiohead.

Executive producer Valerie Aiello said her company did the lullaby tributes because they love the music of all those artists. She said they tested the CDs on babies they knew and she can vouch that one crying baby fell asleep while listening to the Coldplay disc.

The Metallica, Coldplay and Radiohead versions come out Tuesday.

Future editions will feature lullaby versions of Tool, Smashing Pumpkins, Bjork, Nirvana, Queens of the Stone Age, No Doubt, The Pixies and Pink Floyd. Aiello said while a lot of the music works well in this format, some songs just don't work. She said even though "Rape Me" by Nirvana was a hit, it just wasn't the best choice for babies.

The CDs will be available in stores or through the web site www.BabyRockRecords.com.
