What is Lisp good for?

When I hear Bash/Perl/Ruby/Java/C/ML/Erlang/Smalltalk/etc I know what I'm dealing with, I know what they are good for and when to use them, but what about List? Don't get me wrong, I like Lisp, I just don't see for what I could use it.

So, what are you doing with Lisp and why exactly Lisp over any other PL?

See, that's the problem, I learned it, but I don't see for what I can use it. For everything I do there is (in my opinion) a better language.

That's the feeling I get, but people say the same thing about Erlang, OCaml, Smalltalk and many other useful languages, so I'm not so sure.
