SYA had her first break when she was signed to one of the biggest labels in the country as the first female artist signed to Def Jam South East Asia. SYA has always loved writing and has written a few songs and dropped her first freestyle KIKA, in January 2019. Instantly, it became viral, grabbing the attention of Joe Flizzow and SonaOne. In late September 2019, she dropped Berzerk freestyle, unsuspectingly becoming the most viral freestyle she’s made thus far which catapulted her career in music. 

Soon after, she released her singles “PrettyGirlBop” and “MADAME.” She was featured on Def Jam SEA remixes such as “Bad Boyz Remix” and “Orang Lain Remix.” In 2021, she performed her single “PrettyGirlBop” at the Coach x Def Jam SEA virtual concert.
