There are plenty of parts of Nach the christians spend more time reading than jews do 🙁
When was the last time you read Yishaya? All one has to do is walk down the cars of a Subway train and you will always see a few people reading the bible , you will rarely see a frum jew reading Nach. In fact if you walk through the Beis Medrash you will rarely find people learning Yishya or Trei Assar.
Unless someone is a Gadol, I seriosuly doubt they know somewhat obscure pasuks in Shir Hashirum
