Rose Cousins on why staying in love is so hard

On her latest record, “Conditions of Love Vol. 1,” Rose Cousins digs into all the complicated feelings that come with love, from falling in love, to keeping the romance going, to maintaining friendships. It also finds the Canadian singer-songwriter reuniting with one of her most important companions: the piano. Rose sits down with Tom Power to talk about the album and her song “K’s Waltz,” which is an ode to a close friend she lost.
