The world’s most popular genealogy company, last week, teamed with Spotify in hopes of answering a simple, albeit loaded question: “What is the sound of you?” A partnership between Ancestry.com and Spotify still seems unlikely, but the gist of the value proposition is this: Plunk down $99 for the ancestryDNA program, mail in some of your saliva, and Ancestry not only paints a picture (figuratively speaking) of your heritage, but provides a soundtrack to accompany it thanks to Spotify.
