Why lyrics?

Was browsing the latest posts again and I’ve noticed another trend: a lot of people post nothing more than song lyrics. Why is that? Don’t people have anything original to say? Posting song lyrics, to me, is like buying a Hallmark card; a canned way of saying something you can’t think of stating originally yourself. I can see the day in the not-too-distant future when that’s all we do with one another, quote music lyrics, or lines from movies; it’s the way people will communicate in the future.
