The game is missing features from some previous iterations, still runs into some annoying perfrmance issues to this day, and it seems unlikely we'll get another game update in the near future. The game's main setlist is also mostly obscure bands or deeper cuts/newer songs from known bands, but I don't think it's a weak setlist. It just had a very strong legacy to live up to.

However, the game is still getting DLC every week 8 years out, and I still play it constantly. Not the best Rock Band, but the longest lasting and i think that counts for something. Glad the game is still going, even if it's at a much slower pace than the series' heyday.
