Confident by Demi Lovato is a hot new song that has a great beat for dance. There is both an Explicit version and a Clean version on iTunes. However, even the clean version has some lyrics that are not suited for kids.
Squirrel Trench Audio now has three great-sounding edited versions with cleaned lyrics, suitable for all ages and situations, including dance studios, competitions, recitals, and talent shows. Any of these edits is $9.99.
