The Cradle Rock series of music takes your favorite artists and turns their music into melodies that are light and lullaby-ish.....including sounds like a kid's xylophone. One of my favorites is Taylor Swift's "Fearless" album, which, in the Cradle Rock series, is called "Tearless. The latest edition to the series is a baby-fied version of "The Eagles Greatest Hits, Vol. 1 " Fans can play the band's hits for their babies in lullaby form. There are also versions of Michael Jackson music and so many other fun albums with baby titles!
