Why would she concentrate on her hits when she’s over that? That was 8yrs ago, ppl bought tickets for those shows. She knows they want something different, and she has nothing to lose by performing her album cuts. She’s already Janet Jackson.
And judging by how she performed the next day, she wasn’t bothered.
It’s her career, let her run it her way. If you don’t like it, oh well, but you aren’t a world renown entertainer to critiqué what she does.
