Personally, I write songs, and NONE (except one) have been written about the topic of love. Sure, love is a broad word, but I'm fairly certain you get my meaning. I am tired of songs about romantic love especially. There are simply too many topics out there, interesting ones.
I actually don't mind a song about love, as long as it's well written and the music is profound. It's part of human experience after all. But surely an artist has more to say than that.
