Janie released the self-written songs City Lights and Paper Dreams on iTunes and Spotify earlier this month.
Her main goal is to focus attention on the efforts of the Central Otago-based anti-bullying group she belongs to, Sticks 'n Stones, and any proceeds will go towards its work.
Janie plays acoustic guitar and sings in both songs.
They could be described as ''indie folk'', and of the two, City Lights was more overtly about bullying, she said.
She did not know how many listens or downloads she had received online, but said she was ''extremely surprised'' by the amount of positive feedback.
''Sticks 'n Stones is so big now that members all over the place are sharing them.''
Janie wrote the songs in 2014, but said it took time to record and release them.
She has been strumming the guitar since she was 13, but her love for singing stretches back much further.
''Probably since I was about 2. I wanted singing lessons when I was 5, but the music teacher said I was too young.''
The songs were produced by Alexandra musician Matt LaHood, who also teaches Janie guitar.
Janie was one of the founding members of Sticks 'n Stones in 2013.
''I've just always liked the feeling of helping other people.''
She expected to hear from Otago University soon about whether she would be accepted to pursue music as a double major with a bachelor of arts degree next year, she said.
A third song, Sky High, written and recorded by 12-year-old Mount Aspiring College pupils Evie Simon and Red Simpson, was released on behalf of the group at the same time as Jamie's.
Sticks 'n Stones now has more than 300 members aged 11-19, with groups in Wellington, Christchurch and Dunedin.
Group facilitator Karla Sanders said changing the bullying culture meant ''working from the inside out''.
''Traditionally, anti-bullying messages have been created and delivered by adults and tend to focus on the classroom.''
The songs can be found on iTunes and Spotify
