I've had some good luck with surfing the IceCast directory in the sidebar of VLC but it often only helps discover music if they have their id3 tags configured correctly or that the dj is disciplined about doing track IDs
The BBC streams are great about both aspects if your interests are covered by one of their shows
I have some friends in the local scene still who will refer me to local club shows and stuff.
I’ve had a hard time getting really passionate about any new-new acts for the past decade or so though, I blame my age/stage of life more than anything there.
