Sonata Dusk is a member of the demonic siren group, the Dazzlings from the second Equestria Girls movie Rainbow Rocks. Along with her sisters, Adagio Dazzle and Aria Blaze, she plans to use every human's negative energy to be the most powerful siren in every reality, but fails to do so. Adagio finds Sonata the most dimwitted Dazzling due to her constant bickering with Aria.

Her most internet-breaking moment of all is when she looks at a poster on the CHS hallway wall saying "Taco Tuesday." That moment is so popular that there are fanart and cosplay pictures of her loving that Mexican delicacy. On Season 2 of the Equestria Girls web series, the Dazzlings made a return with a music video "Find the Magic." During that music video, Sonata is seen wearing a magenta dress with three tacos on it, meaning that she still loves that delicacy.

We've seen Sonata Dusk go crazy over tacos, but we've never heard her sing about them. Once Hasbro and Boulder Media bring Equestria Girls back, we'll finally get to hear Sonata Dusk sing about her love of tacos. It can either be original or recycled from songs by other artists such as Debbie Gibson, ABBA, Donna Summer, and Miley Cyrus. We Bronies can't wait to hear Sonata sing her solo song for the very first time.
