Please tell me what this indicates,if anything.

I post message in the reply to this message.

I think a young lady on this forum could probably know the answer to this because they will know the psyche of what the young lady will be thinking. She was not expecting to hear such song and was ,I think, shocked they played it.
I know a young lady, we are friends but have no relationship as such, just that we comfort each other, but I know I have feelings for her and I think she has for me, but for various reasons which I wont go into, having a relationship is difficult and thus we are both constrained ,which causes me some angst.
Some while ago she went out with female friends and long and short she said at place they went to in London, a club, they played a certain song with (and I can only presume, explicit lyrics) .She would not tell me what the song they played was, I guess because of content of it ? ,because she said did what want me to listen to it.
I am just trying to get my head around what it indicates that she would not tell me so I can hear the song ?.

maybe she forgot or shes embarrassed or she doesnt want u hearing stuff like that bc she wants u? idk
