Riddle???

Thought, words and rhymes,

So many lines,

Also the voice divine,

Who am I?

Beautiful Creation,

Full of Imagination,

Express character fine,

Who am I?

Form of devotion,

Represents emotion,

Inspiration of mine

Who am I?

Sweeter than sweet,

Closer to Heart beat,

Enjoyable than wine,

Who am I?

Happiness of feeling,

Pain of relieving,

Glow and shine,

Who am I?

Twinkle Twinkle Little Star,

Jack N Jill Went up the Hill,

Can you define?

Who am I?
