Haha it can be frustrating, can't it?
But there's another way to look at it. Having success the charts is no longer a measure of good songwriting. It's a measure of good marketing, and a little luck thrown in. I'm not saying that there are never any good songs in the charts anymore, just that there aren't many...
But here's my analogy. So many chart-topping acts are here today, gone tomorrow. They have a small bit of success and then no-one hears from them again. Kind of like a newspaper article.
Good music is still around years after its release, and the people who made it are generally involved in making music permanently. Their music is like literature. There may be a dwindling demand for it, but that's no reason to stop making it, right?
What would you rather make: a tabloid story or a work of literature?
I know where I stand. Let the chart-toppers have their silly dances; we have art to make!
