It's hard to write any good song. It seems more rewarding, or maybe just easier, to write sad ones.
I don't like to think about stuff that's boring.
I don't think anyone wants to do the same thing over and over again.
I think you just have to have some rapport with the song.
As a producer you can be more objective about the songs because you didn't write them.
My songs, well, they are sad, but in all of them the person singing them - me or whoever - is actually still trying and hasn't given up yet.
