Maia of music, hide no longer!

[Encaitare]

Did Melkor do any more singing once the Ainulindale was complete? I have a mental picture of him sort of dropping it and 'moving on' to darkness and dastardly plotting, no music involved. Did Morgoth sing back to Luthien?

This sparks an interesting idea... perhaps he used some form of music for evil -- maybe that was part of Morgoth's "slow arts of cruelty" in creating the orcs. Maybe it was the deed "most hateful to Iluvatar" in part because he turned the music that Iluvatar gave the Ainur to such terrible purpose.
