What female artist sang that song in the current Subaru Outback commercial?

This commercial is still currently on TV. It's a commercial for the Subaru Outback. The song sounds like an oldie, slightly country (similar to Patsy Cline). It's a beautiful tune, the lyrics are "I've been looking and looking my whole life through, trying to find my way back to you - becuase I love you, I do." I would love to know who sings this song...where I could find it, or the name of the album. And if anyone has suggestions of similar female artists that sound like this artist, do tell. Thanks!
