It's like hearing a song in your head, you can listen to it and maybe keep time roughly but if someone asks you what instruments there are you might not be able to get all of them, or might not remember the drums or the baseline. It's all much more vague. If you asked me to remember my childhood home I can visualise 'all of it' in my head, but maybe not what the type of bricks are like, or where all of the windows were.

This actually highlights to me what may be different about mental images for other people. Because I can much more clearly hear music in my head than I can see images in my head. So if it's much more vague for others, that must be kind of what images are like for me.

For me images are clear and easy, sound is limited and more difficult.

Not quite. I have had a lot of musical training and have a very good musical memory. I can write down songs from my head or hear a song and write it down later, depending on how complicated it is, usually with only 1-2 listens, or play it back, etc. I can visualize things in my head but it is a lot more abstract, or rather, harder to explain.

I think the person you're replying to didn't describe it exactly. It's not really about how good your memory is, I think. It's that no matter what, "replaying" the song in your head isn't going to bring about the same reaction as actually physically hearing music. It's like a simulation, a higher-order perception, thinking of yourself hearing it rather than willing yourself to really hear it in the same way as usual.
