The one you need
Yes, Tapestry is the highlight, and requires only half the credits to buy, but this is the one to get. An utterly charming overview of her skills as a writer and performer. There's a reason why she has sold 20 million records - she's that good, and it's not just Tapestry. Even if you don't know all of these songs, you will soon, because you're going to play this over and over.
