Indie kiddie rockers Charity and the JAMband have recently launched a Song of the Month feature on their website. The first free download is their sweet, charming rendition of Twinkle Twinkle Little Star. Visit this site and pick up some swell kid's music for free then plop it right into your iTunes Library for easy playback whenever your kids want to hear it.
You'll probably want to bookmark the Song of the Month page (or sign up for email updates) and then stop back monthly for more freebies. By the end of next year you'll have compiled a complete album's worth of awesome Charity and the JAMband children's music entirely for free...Sweet!
