Why is finding happy upbeat songs so hard to do?

They are always on the radio (the same ones over and over)

But as soon as you try to find one alone they are like

Endangered animals-you have to hunt them down

And they all sound the same

But they are nice to listen to anyways

With their banjo-harmonica-synth-keytar-tambourine beat

like camouflage-a moth blending into a tree or something

I think i listen to those happy top 40 songs

Because they are what is now natural
