I think the point in question is that you are not cracking *MD5*. That
would entail finding a weakness in the MD5 algorithm that allowed you to
reverse the hash, or more easily find what created the hash you are
looking at.
Using rainbow tables and such is just brute force, and doesn't have a
lot to do with the specific hashing algorithm.
