Janet Ava Leon (born October 19, 1990) hails from Gothenburg, Sweden, and joined the pop group Play in late 2003. After Play's lead singer Faye Hamlin left the group to pursue further schooling in October 2003, Janet received a phone call from Play's manager, Laila Bagge, to whom she had sent an audition video in the past.

Janet had also been an acquaintance of original member Anais Lameche prior to joining Play. After meeting Janet, the three remaining members of Play, Anais Lameche, Rosie Munter, and Anna Sundstrand welcomed her into the group.

On December 15, 2003, an official press release announced that Janet had officially joined the group and had begun recording a new album with them.Previously, Janet had been part of a band with some friends called "Walking Spanish," that had performed at music festivals around Sweden.

Janet stepped into Play as the new lead singer and mezzo-soprano power vocalist, though she was the youngest member of the group. Janet's first album as a part of Play, Don't Stop the Music, was released on March 9, 2004.

A subsequent Christmas album followed in November entitled Play Around the Christmas Tree. Janet appeared in two Play music videos, both for the song "everGirl."Recently, Janet has been doing some solo work, recording a song for Build-a-Bear Workshop and another song for Kohl's clothing brand everGirl.

She also recorded songs for the 2005 Rock Angelz music album to promote the Bratz dolls franchise. She was featured on the Lindsay Lohan remake "Change the World" (background vocals) and lent her vocals in the song "Nobody's Girl".

Since the members of Play formalized the group's breakup in September 2005, Janet has been communicating with fans about her efforts to record and release a solo CD.
