copyright generally applies to exact matches or really really close ones. The more iconic, the greater the leeway in determining the match.

The real fact of the matter is, MONEY. The only way you would face any sort of issue would be if the song made lots and lots of 7 digit kind of money. Since it not very likely that the song would earn even low 3 digit money, I think you're relatively safe using that "not quite exact" phrase that kind of sounds like one from an iconic movie.

Generally, if you're not making money from the song, you get a letter demanding that you cease and desist, or they ask YouTube to remove it. It's only when there's a fair amount of money being made that the letter says "see you in court".


I'm not a lawyer so take that advice at your own risk.
