Is there a technical name for people who can absorb and remember song lyrics?
Not that I know of. I can’t remember much full stop. Apart from exact prices of supermarket products when I see them and want to tell people about it. I have aspergers and have a good memory for certain things. Some people just aren’t great at remembering lyrics or other things like quotes from books etc. We all have different things we’re good at doing. It’s not something to get worked up and worried about. You just have to accept that it’s something you’re not great at.
