Jayn—otherwise known by her online moniker, LittleJayneyCakes—is an American singer/songwriter and producer, specializing in acoustic works and covers.

Her musical career would begin January 2010 when she uploaded her first video to her YouTube channel—a music box cover of InuYasha’s “With You.” After the cover’s release, Jayn continued with anime-themed works, releasing several similar tracks, including the Gravity Falls theme, which would kickstart her popularity, gaining over 1 million views. She would later cover The Living Tombstone’s “Discord,” kickstarting their relationship.

Jayn continued covering tracks—including one of her most popular pieces, her Undertale tribute, “Mega Stronger Than You.” However, she also started uploading original songs, her first being November 2015’s “Smoke and Mirrors,” becoming her most popular YouTube video and Spotify song, sung from the perspective of a psychopath-turned Yandere. From then, she became a popular name in internet artist conversations, later being sparked by her feature on The Living Tombstone’s January 2017 Overwatch-inspired parody, “No Mercy,” a 2017-18 meme phenomenon.
