Not the guy you’re replying to, but his description matches my experience.

I can’t hum songs anymore complicated than the “Happy Birthday” song (but if it plays, I’ll recognize it).

I can’t remember people’s voices in my head (but if I hear them speaking, I’ll recognize it is them).

The bang of a fireworks or a car going by is simple enough to recall. It is also generic. I might not remember the hum of the engine of a specific car, or be able to play back a specific fireworks display.

Yes, this is essentially my experience. I can't recall sound, but if I may "tag" features to a sound so that I can somewhat imagine it.

Like the idea of a firework bang, being low intense vibrations, or a car horn being a high pitched short startling sound. Still can't really imagine it like I can picture things in my head, but I have an idea of the what the experience would be like.

Same here. Plus aphantasia.

Explains why I had such difficulty singing my whole life. It must be way easier if you can just recall a song in your head and match its pitch!

I cannot sing but I can create songs in my head including multiple instruments and vocalists. Admittedly, I have given singing very little effort past age 8.
