Thread: finish and finish up

The difference here is one of euphony -- i.e., which one "sounds more attractive"? -- and of course, that's very subjective. Some people would say that using "up" improves the rhythm of the sentence, and makes the sentence flow more easily from the lips; others would disagree. But either way, it's a question of aesthetics, not grammar.

Am I totally wrong with my understanding of the differences?
