On July 11, 2026, both "Cutie Mew Mew Magic" and "Flower Man" from Chapter 5 became developer and composer Toby Fox's first two songs to reach the Billboard charts, used to catalog popular songs in the United States. Both songs appeared on the Hot Dance/Electronic Songs Chart, with the former debuting at No. 18 and the latter debuting at No. 13. While soundtrack albums for Deltarune's prior chapters previously appeared on the Billboard soundtrack charts, this marked the first time where individual songs from one of Toby Fox's games charted.
