Sheet Music finds Nancy Sinatra giving luxurious, laid-back readings of a variety of romantic songs. She concentrates on ’60s pop and pop/rock songs, from “Light My Fire” and “Something” to “Tired of Waiting for You” and “Shadow of Your Smile,” throwing in some traditional pop tunes like “In the Wee Small Hours” along the way. Sinatra never had a terrific voice, but it was charming, and that was enough to sustain her through her ’60s records. As she aged, it grew weaker, but on Sheet Music, she’s carried by the lush arrangements, which draw attention away from her thinning voice. It’s enough to make the record a pleasant experience for her longtime fans. – Stephen Thomas Erlewine
