It's hard to really articulate what the parameters are that make one song parody-able and another song not, but if I can come up with a good enough idea for it, I go for it, and if not, then I have to move on.
There's a lot of different ways that a song would be a challenge to parody. There are a lot of songs that would ostensibly be a good candidate for parody, yet I can't think of a clever enough idea. Some songs are too repetitive for me to be able to fashion a humorous set of lyrics around. Some songs flat-out just don't work creatively for me.
I like to think that I've gotten better at what I do. I spend more time and pay more attention to detail album after album. But pretty much it's stayed the same.
I'm a music fan, and I can listen to the radio, or music, without thinking, "How am I going to screw this up?" [Laughs] If I'm really actively trying to think of a parody, then I'll have my antenna out, and be a little more proactive about it.
It becomes more important to me as time goes on to make every album the best thing I've ever done, so it's a lot of self-imposed pressure that also kind of slows me down a bit.
Many years ago I found out something about hamburgers that really grossed me out. You may not know this, so I hope I don’t make you sick, but it turns out hamburgers are actually made out of dead cows. I am not making this up. Needless to say, as soon as I discovered that, I gave up meat entirely.
