I don't think that's a fair assessment, considering that they only bother with this band for fun. It's hardly a major project with lots of thought put into it, haha. I recall reading in an interview that they just go into the studio for a weekend or two, drink a whole lot, and the process for songs goes something like this:
- Pick a song.
- Decide whether or not the song should be faster than the original, or about the same tempo.
- Try it.
- If it doesn't work after a few takes? Move on.
