Can I compare the contents of one folder with another?

Here's what I need and I'm not sure how I'd do it so I thought I'd ask, since I'm new to macs.

I have a hard drive with mp3's on it. Each artist has it's own folder with their albums located inside. What I want to do is print or compile a text file [or whatever you recommend] just the Artist folder with another folder to determine what Artist's I'm missing on the one hard drive.

Not sure if this makes since but if you need more answers, just ask.

Thanks in advance!

 

That's cool that it's built into OSX SL, but I may find it difficult to input the directories. My folders I want to compare are located on different hard drives. So I'm not sure what to type in Terminal. Since I don't understand command line programming I can't tell it where to go.
