Song for the ghost giant

The idea i have is to have this story of a ghost giant with an affinity for collecting letters and write a relevent song that goes with the story.

("Ive got so much to say,
But cannot open my mouth,
I hide away in the day,
And ponder my thoughts in a lonely house,
See im from around here but you wouldn't know,
Because i lost my friends a long time ago,
I collect letters every night,
And even if i could spell i wouldn't know what to write.")
