Being known incessantly as the daughter of Loudon and the sister of Rufus must get on Martha Wainwright’s nerves. Still, she compensates by singing angsty and belly-button gazing songs filled with sorrow and anger on her new album, I Know You’re Married But I’ve Got Feelings Too.

Successful at capturing a mood, like the songs featured in the underrated Laura Linney-Topher Grace film P.S., Wainwright sometimes stumbles into same-iness and self-pity. At her best, in songs like, “You Cheated Me” and “Niger River,” Wainwright’s intelligence and wit shine through and lift the material above the girl-in-a-coffee-shop genre.

At worst, in songs like “In the Middle of the Night,” Wainwright’s screechiness and vitriol feel like a bad Alanis Morissette parody.
