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.
My process for the parodies is that I get an idea for a song and then get approval from the artist and then go in and record it and probably try to get it out as soon as possible.
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.
I do original songs in the style of other artists, where I try to learn all their musical idiosyncrasies and try to do something that sounds like them and yet is a bit more sick and twisted.
I did have a child, and I was reading a lot of picture books to her, but at the same time writing a children's book was something that I'd been wanting to do for many years, pretty much since the start of my career.
