The past is a different country. In the 1980s, it was indeed very strange to do that, especially in the official names of songs and albums. It was something kids or the illiterate did. It was embarrassing for an adult to use 4 for 'for' in anything important, even art. Today, that is not strange at all, it is common slang. Prince is one of the reasons why we don't see that as strange today. He was one of the first to (re)introduce doing that on purpose in a major work of popular culture.
