Depends what you're looking for. If you're a casual listener and don't care that much about music then you're right to use Demonoid, slsk and the like. In fact, grab a program called BitChe and you should be very happy.
But if you're serious about music then you're not going to find anything that rivals dedicated trackers like What & Waffles (and definitely not the more elusive music trackers). The main difference is simply the amount of material. Any artist you like, odds are you'll be able to find everything they've ever done. I've used every p2p option you can name and I'm still constantly amazed at at the depth of the selection on these sites. There's no comparison whatsoever.
That said, I still keep Emule around.
