I think a difference in modern alternative radio compared to previous eras is the broadening of the term "alternative", specifically the difference between it and "alternative rock". If WRFF wants to be an "alternative" station and play, say, Billie Eilish, or other artists who push the limits of their format, they can. It seems like most major modern alternative stations have taken that approach. It's not what I'm used to, not what I prefer, so I wouldn't listen, but that isn't to say other folks won't listen. It's harder for me to grasp how Eminem or Outkast could be considered "alternative". Granted, some alternative stations were playing Eminem at the time of his debut (certainly pre-"Lose Yourself" which is what iHeart alt stations seem to spin), but "Hey Ya" is a straight up pop song that is way closer to a Hot AC track than Alternative (or even classic alternative at this point).
