I've found damn near every band on vibrations of doom, cruz del sur, and barbarian wrath on dc++. Not to mention every Vincent Price film AND even those obscure cartoons, like fern gully (which isn't too rare now, but try about five years ago... it was insane). Torrents are also extremely unreliable.
Also, it's fucking perfect for comics.
TV shows might be what torrents are best for... still, i've found dc++ exceptionally useful for shows. The main reason I stopped using dc++ and started using torrents is because I ended up downloading wayyyyy too much with dc++. it was just an endless stream of data!
