Which isn't to say we don't love Cash's 21 Top 40 Country hits. "Seven Year Ache" is the smartest musical memory to linger from pop radio's lamentable early '80s romance with country music, and her version of John Hiatt's "Runaway Train" was a high point in both their careers. But it's fair to say that, ever since 1979's Right or Wrong, she's made gloomily sophisticated music fashionable in a way that Laura Nyro never could; helped reshape what country music sounds like; and has upheld the singer-songwriter tradition in a world overrun with Shanias and Faiths and LeAnns. For that, and for all the hits, and the gorgeous ruminations wedged between them, we're deeply grateful.
