About Music and One's Attitude Toward It

On Yahoo News I read an interesting article about music marketing.
According to the article people are becoming less interested in paying to listen to new songs.
While the article partly attributes it to music's free online availability,
it also suspects that one's attitude toward music is fundamentally changing.

For example, the article divides music listeners into four categories:

1) Those willing to pay for music
2) Those only interested in music if it's free
3) Those only interested in music that's free, and that they are already familiar with
4) Those uninterested in music

The article argues that while Category 1) is surely diminishing over the course of time,
that Category 3) and 4) are becoming more and more dominant.

The bad news for the industry is that Category 2) has been slowly diminishing
even with the teenage demographic, which traditionally has been the most important target.
The article suspects that young listeners nowadays have already been surrounded with an overwhelming amount of music, and they don't hunger for more.

The article concludes that something needs to be done in order to tap this most potentially lucrative market.

To be honest, I am surprised to read the article, because when I look back on it,
my teenage days and early twenties couldn't possibly have existed without music.
I would stay up all night making cassette tapes with my favorite songs in them,
with a prospect of listening to them with my favorite gal while driving, of course.
Music is always inseparably associated with my romantic memories of the past.
But then, why the gradual decline in the interest in music among the young demographic?
I don't know.
That's for the industry to figure out, because if they don't, they will be in big, big, trouble.
