Okay, I'll keep it similarly simple:

Music: the science or art of ordering tones or sounds in succession, in combination, and in temporal relationships to produce a composition having unity and continuity b : vocal, instrumental, or mechanical sounds having rhythm, melody, or harmony

art: the conscious use of skill and creative imagination especially in the production of aesthetic objects; also : works so produced

poetry: metrical writing : VERSE b : the productions of a poet : POEMS
2 : writing that formulates a concentrated imaginative awareness of experience in language chosen and arranged to create a specific emotional response through meaning, sound, and rhythm

There is nothing in any of those definitions about quality, success, peers, concensus, awards, or public recognition.

Your use of the word literature is correct in this context, as it applies to a special class of written works with specific attrributes: writings in prose or verse; especially : writings having excellence of form or expression and expressing ideas of permanent or universal interest (2) : an example of such writings b : the body of written works produced in a particular language, country, or age c : the body of writings on a particular subject d : printed matter (as leaflets or circulars)

But I have never said, hinted, implied, or alluded to an opinion that all written works qualify as literature. They do not; however, all written works are inherently "writing."

Cite your source. Show some articles that back up your opinion that something is not art unless it is deemed "quality" by general or peer consensus. Give me a dictionary or encyclopedia entry that backs up your definition of art.
