It works just as well with music as it does with comedy websites staffed almost exclusively by winos. If you can't find anything to listen to, just turn the Internet on. The rest should take care of itself.
That's why claims of "There's no good music anymore!" should be treated as one thing only ... a cry for help. This is an increasingly computer-centric world we live in. If you can't use one to keep you entertained in whatever capacity is going to do the trick, you might as well just stop trying anything. Hell, even mom can fire up a game of solitaire on the laptop if she gets bored. Finding new music isn't much of a stretch from that.
Granted, if you started your search for new music sometime before the Internet happened, I can see why you might have given up at some point and just resigned yourself to a life of listening to Bon Jovi (who are awful by the way, so, you know, glass houses and shit) while you drive your kids to soccer practice. But even then, it's not rocket science. You can find anything on the Internet, and bands making music you enjoy are no exception.
