Help finding duplicate files

Is there a tool that will remove duplicate files from a hard drive? Because I download a lot of music both karaoke and regular and because a lot of cd’s both karaoke and regular have duplicate songs on them i end up with a shit load of duplicates on my hard drives taking up room.

Is there a software or downloadable tool that will go through my hard dives and remove duplicate songs?

This is a pretty good all around utility. There is an option to find and delete duplicate files.
