Sia recently appeared in the new song "Waterfalls" by Norwegian duo Stargate along with P!nk for Stargate's debut album and she currently has the song "Move Your Body" out as her latest single. It's not everyday the Australian songwriter shows her face, but she did just that when she appeared on PBS' "Sesame Street" to sing about her love of music.

The pop star joined some of the show's most known characters singing "'S' is for Songs" while showing her face wearing her signature black and blonde wig with a gigantic pink bow on top of her head. Characters like Grover, Elmo and Cookie Monster also joined in on the fun with those wigs as well as she sang, "'S' is for songs/ And I love songs/ Don't know what I would do without them/ I love songs so much/ I wanna sing a song about them." The short clip is reminiscent of Sia's vague reggae pop vibe singing, "I wanna sing about high songs/ And low songs/ Fast songs/ And slow songs." Her crew joining in singing with her do their part in harmonizing while having fun.

Sia has reached out to the younger audience not only through "Sesame Street" but in the upcoming animated film, "My Little Pony: The Movie." She will be voicing the character Songbird Serenade and is a pegasus modeled after her stage persona. Additionally, Sia will be contributing two original songs to the soundtrack with the film set for a Oct. 6, 2017 release.

The Australian's most recent single "Move Your Body" hasn't had the push that previous songs did such as the No. 1 "Cheap Thrills" featuring Sean Paul. It's been released with a single mix in January and has only reached No. 1 on the Dance Club Songs chart. Elsewhere, the song has not charted. Previous single "The Greatest" released in September 2016 hit a peak of No. 18 on the Hot 100 songs chart while reaching No. 10 on Pop Songs, known as Mainstream Top 40.
