Sometimes, if I don’t know the lyrics of a song and don’t want to look them up right away, I just try to find something that makes sense. Sometime later, I finally look at the real lyrics and compare them to what I was singing all the time. It happened a few times that I liked my version more or didn’t understand the real ones so I just changed the lyrics whenever I sang the songs But I also do that unintentionally sometimes, even if I know the real lyrics.
Do you sometimes change the lyrics (on purpose) when you sing a song?
