A lot of things ended up going into more procedural memory than I was expecting. I can't actually tell you how I was able to still log into my online accounts with my password - I suspect muscle memory has a lot to do with it. I often will have a sense if I knew a person if I see a picture of them or I read their name, but sometimes linking it further than that goes nowhere. Music/language is interesting, yet mostly expected. You're probably familiar with the case of Scott Adams, who worked on overcoming Spasmodic dysphonia using a nursery rhyme. So certainly different pathways there - I will remember tunes, lyrics (even in languages that I can barely use anymore), but not the context, artist, etc. I can read all the non-latin scripts that I used to be able to read.
