For the past few years Spotify’s Discover Weekly has been the main way I discover new (to me) music. Secondarily I guess just from browsing the related artists of the ones I already listen to. Looking for other strategies inside or outside of spotify.
@MothraCultist shared the website www.rateyourmusic.com in another thread the other day. I spent some time there and found it quite helpful to find new albums and see their community ratings.
