Ms. Rachel, the children's entertainer behind the Songs for Littles series, has announced her debut album, I'm So Happy, due out on 25 September via Magic Star, the children's and family division of Sony Music's The Orchard. It marks the first full-length record from Rachel and Aron Accurso, the married couple who co-created the hugely popular Ms. Rachel franchise, and cements the brand's growth from a YouTube channel into a major multimedia children's entertainment property.

The 23-track album blends original songs such as "I'm So Happy" and "Big Feelings" with reworked children's classics including "Hop Little Bunnies" and "Icky Sticky Bubblegum," closing with tracks like "B-I-N-G-O" and "I Love You to the Moon." The lead single, a bossa nova-styled song called "I Love a Rainbow," is out now. Rachel Accurso, a former preschool music teacher with dual master's degrees in early childhood and music education, created the series in 2019 to support her son's speech delay, while Aron brings a Broadway composing background; the show has since earned two Children's & Family Emmy nominations and became Netflix's most-watched children's season in early 2025.
