For mending a bruised heart "I've created a lot of breakup playlists for friends. One of my standbys is 'You Wanted It,' by MoZella. I first heard it in an airport bathroom when I was going through a situation with a guy—I'd thought he was in, but he was just chasing me for the sake of the chase. This song sounds like she can empathize."
For making yourself at home "I'm a big fan of 'A Little Opera Goes a Long Way,' by Sky Sailing: [sings] Pretend you're not alone / Like you are center stage on Broadway / 'Cause when you are on your own / A little opera goes a long way. That was my theme song for the first few days of living solo."
For feeling creative "My 18-year-old brother turned me on to the Icelandic band Sigur Rós—they make me happy and take me away to dreamland. I love trying to memorize the words, even though they're singing in their own language. Sometimes I'll make up some lyrics. It gets pretty interesting."
For pondering a certain four-letter word "I have a playlist called Happily Ever that's 30 songs deep, all about love: 'Until You,' by Dave Barnes, 'Rain,' by Patty Griffin, 'Easy Silence,' by the Dixie Chicks. When I listen to 'Naked as We Came,' by Iron and Wine, I hang on every word and dissect every metaphor; I'm completely absorbed."
