Song of Solomon: Interpretation

1. "The song of songs, which is Solomon's."
   The author claims to be Solomon. He isn't. The Song of Solomon (aka "The Song of Songs") was written (forged) several hundred years after Solomon died (if he ever lived, that is). 1:1
2. "I have drunk my wine ... O friends; drink, yea, drink abundantly."
   Is it OK to drink alcohol? 5:1
