Bible-believing Christians & Jews: How do you interpret the Song of Solomon, aka "Song of Songs"?

I'm not sure where the idea that it deals with the Queen of Sheba comes from. It deals with a Shulammite girl (a country girl from Shunem, or Shulem) and her love for a shepherd boy; and King Solomon’s unsuccessful attempt to capture her love. The book illustrates the beauty of enduring and constant love, fidelity etc. It also shows that the Bible doesn't support prudishness as far as expressing affection. ;-P
