I tend to enunciate pretty well. It's always seemed that my voice is one of those voices that people can recognize pretty easily - which has been a bit of a drawback for some characters because you're supposed to lose yourself in the character, but sometimes people look at a character and go "Oh, it's 'Weird Al.'"
I've always known that if I recorded an album, it would come out, and people would enjoy it! Whereas if I wrote a movie script, chances are better than even that I'd just be another guy in L.A. with a movie script in his drawer.
I have very mixed feelings about it. On one hand, I’m concerned that the rampant downloading of my copyright-protected material over the Internet is severely eating into my album sales and having a decidedly adverse effect on my career. On the other hand, I can get all the Metallica songs I want for FREE! WOW!
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.
In fact, when I come up with an idea for a parody I try to resist the urge to Google the idea to see if someone has done it already because the answer is almost always, "Yes, of course they have, they've thought of it!"
That's a big part of my life - doing things that I'm not prepared to do. Doing things that I don't know how to do, and keep doing them until I get good at them. I always try to put myself out of my comfort zone and out of my depth, and hopefully somewhere along the line I'll catch up.
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.
I make charts of songs that are good candidates, good targets, so to speak. Then I try to come up with ideas for parodies. And 99% of those ideas are horrible.
