In 2015, Alexa began experimenting with her sound, leaving the "Rugged Pop" sound behind for a sound rooted in Urban Pop. Working with Th3ory of The Penhouse, Alexa wrote and recorded a number of songs including 2016's "Hit The Switch", co-written by Travis Bruce. “Hit The Switch” is one of Alexa's most successful songs with over 30,000 Soundcloud streams to date. Alexa also found success behind-the-scenes as a songwriter, co-writing Moka Blast's single “Vida Loca”, which features DreamKayris & The Voice Brasil's Nikki.
Throughout 2017 and 2018, Alexa took pride in solo-songwriting, continuing to create music on her own terms. In April 2019, Alexa released the single "Can't Help Myself", produced by Til December. "Can't Help Myself" showcases the evolution of Alexa's artistry as an Urban Popstar, & as a songwriter, as she continues to build her path in the music industry.
