While the world continues to obsess over Taylor Swift’s “1989,” Swift is obsessing over a fan’s mashup of her own tracks, “Blank Space” and “Style.”

Swift shared the mashup, crafted by Nashville-based artist Louisa Wendorff along with Devin Dawson, on Saturday with the simple declaration, “OBSESSED.” A harmony-driven acoustic cover, effortlessly splitting into their own melodies at moments, the mashup would seem like a single song without any prior knowledge of Swift’s tracks.

OBSESSED.

To say the least, Wendorff was shocked and ecstatic about Swift’s sudden support, asking her Twitter followers the age-old question, “WHAT IS LIFE?!?!”

You can hear more covers by Wendroff on her YouTube channel, and fans can expect some new original material from her in 2015.
