Barely any songs are officially released on streaming platforms such as Spotify or Youtube which is a shame.
However I said "officially" most songs have been uploaded to youtube so look some up if you would like to give her music a try!
The only ways to officially listen to the music is by buying either digital copies from her booth site or by buying physical CDs.
Finding the links and such isn't the most straightforward thing, and since I don't know if I am allowed to link those sites.
I will link her official youtube channel, which has the other important official links in the "About" section.
