A song is not just a collection of melodic riffs, it is an emotional statement. - Andrew Sega

There may not be a high-level purpose for humanity, but that doesn't mean we can't find inspiration in the world. I think there is a combination of psychological and environmental factors that combine to create various urges in humanity -- most importantly the urge to create, to contribute something to the world, to express your personal worldview and see how the world responds. Art doesn't happen in a vacuum, and if it were only for personal gain then nobody would ever release music to the public. The process changes you, and also changes the world itself, creating ripples of inspiration which flow between the artist and the listener.

I think there are some objective [musical] qualities... how complex something is, how melodic, how diverse the tonality is, et cetera. But I could also make a piece of music that contains all of those and yet isn't "good" from a subjective viewpoint. For example, take Beethoven's "Moonlight Sonata", Beatles "Yesterday", and Underworld's "Born Slippy", and play them all on top of each other at the same time. Great music in their own right, but terrible sounding together.

If someone gave me a million dollars to run a music label, I would focus on creating a specific artistic point of view, and creating some channel to build a fanbase. Warp Records was a great example of a label that had a particular style, and many people would buy records just because the artists were associated with the label.
