You know what's cooler than an acoustic cover of a Taylor Swift song? An acoustic mashup of two Taylor Swift songs!

Last week, musicians Louisa Wendorff and Devin Dawson posted a beautiful rendition of Blank Space and Style, both from Taylor Swift's album1989, and it has amassed more than 1.3 million views since.

More importantly, however, Taylor Swift herself approves of the song — in fact, according to her Sunday tweet, she's obsessed with it.

The mashup itself does a great job at melding the two songs together, but we recommend several listens until it really sinks in.

And if you're aching for more such wizardry, check out Louisa's mashup of three songs from August: Beyonce's Pretty Hurts, Colbie Caillat's Try and Jessie J's Who You Are, below.
