I interpreted the question as Which bands had the greatest impact on culture at large?
Of course, this is debatable, but I tried to limit it to which ones influenced the larger culture, and not limit it to which ones influenced subsequent musical directions or other bands.
I think that's what the original question meant. Billie Eilish has not been around to influence other musicians. For that, I would pick Taylor Swift. (She has also been very influential on culture at large.)
Another thing is that the question is the "last" musician who was influential, not the most influential since "fill in the blanks." If the question is the most influential, then the Beatles and Michael Jackson are the top two both in broader culture and the future direction of music.
