Discrimination against old songs

Have you ever heard of someone dis-sing a song

by saying something like

-That is so old!-

or

-How old are these songs?-

So

what is actually wrong with

an old song?

I suppose it's just because

it's not on the charts anymore

cos it's old

making it appear less popular

therefore not as good.

I enjoy listening to old songs

NOT

Mozart's 5th Symphony or something from the 18th century

but maybe

songs only 3-1 years old.

What's wrong with that?

Even if it was a chart topper 3 years ago

people still dis it

because it's old.

It's called discrimination against old songs.
