Listening to "new" music takes time and effort, and is usually genre specific to one's likes. I have always liked indie rock. If you want to hear new music, best thing to do is to do what always had to be done - listen to college radio. I enjoy streaming college radio stations from Univs. of NC State (WKNC), LSU (KLSU), Texas (KVRX), and Georgia (WUOG). Hear a song, and pop over to a streaming service to find it, (I'm on Apple Music), and listen to their catalog, and build playlists. If you want to go even deeper into it, go to Bandcamp where young artists can publish before they take the next step. My heart goes out to young bands who had their bigger source of income - touring - shut down by the pandemic.
The old music is great - songs are a time capsule to memories of youth, but I'd rather hear the musical art of young folks than old folks.
