42 is the "The Answer to Life, the Universe, and Everything" in The Hitchhiker's Guide to the Galaxy.
In the story, a "simple answer" to The Ultimate Question is requested from the computer Deep Thought, specially built for this purpose. It takes Deep Thought 7½ million years to compute and check the answer, which turns out to be 42. Unfortunately, The Ultimate Question itself is unknown, suggesting on an allegorical level that it is more important to ask the right questions than to seek definite answers.
it's a take off of hitchhiker's guide and radiohead's "paranoid android" (which, in turn, was also a take-off of hitchhiker's guide, as was "don't panic" off of parachutes). There's no obvious track title considering the odd structure and lyrics and since 42 and paranoid are both three-part songs... it's all the more appropiate.
"And since I fell for that spell,I'm living here as well' for me these lyrics say that we all live in someone's mind,not only dead people.Have you ever thought that we all might be a part of a bigger someone?
