MarzGurl Sings by MarzGurl started with an a Capella theme song of her own design on Youtube. She made a song where she would sing and not use lyrics. In the videos, she just goes with the melody. After a live World of Warcraft session where she sang "One Winged Angel" in the same format, she announced that she would bring these songs to TGWTG.com. Ever since, she has produced songs where she would go along with the melody of various video games.
