I like singer-songwriters, and I find sad songs comforting rather than depressing. It makes you realise you're not alone in the world.

I don't wanta do any Blues or any sad songs.

It's fun to sing sad songs. And it's fun to listen to sad songs. Enjoyable. Satisfying. Something.

So don't fall in love, there's just too much to lose; if you're given the chance then I'm begging you choose to walk away, walk away, don't let it get you. I can't bear to see the same thing happen to you.

Happy songs are very difficult to write. How many truly great upbeat songs are there?

It's much easier to write when you're sad. But you can end up isolated and depressed because you almost need to put yourself in that situation to have that angst to write from.
