How much music does Apple Music Replay counts?

Hello, was wondering if the Apple Music replay ONLY counts the music saved in the library or ALL music I listen throughout the year (even the albums and singles I don’t save and the ones I delete later on from the library).

I’m quite interested in statistics and yearly data about the amount of albums/minutes of music I listen, genres and so on… but sometimes when I don’t like the entire album I just listened I delete it from the library. Does that still count as listened? Or does the data resets as if I never spent those hours listening to music I ended up disliking and deleting? I’d really like to know. They don’t appear in recently played, but I don’t care about that. I do care that my numbers at the end of the year are as correct as possible. Anyone can help??

thanks
