I listen to both old and new Alternative music as well, and I think things have been on the upswing in recent months. Diversity of genre is up, we have a good mix of veteran and new artists making waves on the format, the rock bent is stronger than it's been for the last 5 years, but we're still getting some decent pop and rap tracks too.If you like it, good for you. But as somebody who listens to both old and new music in the genre, I don't think new music in the "alternative" genre is necessarily low quality. (I can't comment on the 98.7's playlist, as I don't listen to the station.)
My primary issue with Audacy is their over-reliance on some truly awful songs that happened to become hits in 2018-20 (which for some reason tend to be called "currents" and "modern" around these parts even though they're golds/recurrent). They also have a strange tendency to push the worst songs available on the Alternative format the hardest - which means some of that great music that is charting right now can't get past 5th place on the BB/MB charts in the most favorable scenario - and obviously tend to peak worse than that.
It gives the impression that Audacy's Alternatives are largely in their own world and they so happen to share a format with everyone else.
