If you say 'I'm going to cut this song because I know the teenagers are going to love it ' well then you're going to alienate everybody else. When I cut my record I'm just going to cut the things that I like and whoever likes it likes it. That's too much work to try to figure out the demographic. That's too much like a business.
I believe in the institution of marriage. Of course being a Mormon we believe in eternity rather than just till death do us part. If you really try hard if you make it work it's blissful. But I also know a marriage that isn't working can be painful.
