No, but then you are missing out on a powerful element of songwriting. If you write lyrics that are smart and clever, while still being quite clear to the listener it can really emphasize the emotions and imagery of the song.
You don't always need to have the whole thing be completely clear, but the right line in the right place can still make a song much better even if the rest of it doesn't have the same immediacy.
IMHO I feel lyrics that are too complicated or nonsensical lyrically just don't make the emotional impact that clearly decipherable lyrics do. That is why most hits do make sense, even if a lot of them have modestly simple lyrics.
