I am debating taking my first accounting course again?

I give up.  Are you?  Maybe you should take your first Composition course again so you can learn what a question is.

Talk to your advisor about what you should do, not to your classmates.

I'm not sure how a 59% is passing?  Here, that would be a failing grade.  If bumped up a little, it would be a D - some schools don't allow grades of D to count toward your major requirements (although my state now requires us to allow them, so there's that...).  Anyway, depending on the policy of your school you may be able to replace that grade with a better grade upon retaking the course.  Again though, this should be discussed with your advisor. 

If you don't understand the concepts it seems that you will continue to struggle moving forward, so retaking it sounds like a good idea.

What country? In the U.S. a 59% is failing; and even a low pass (65-69%) is not high enough to move forward in your studies. 

My answer would depend on your grasp of the subject matter. If you think you have a basic grasp of the concepts and just had a bad day on the exam, I'd say go ahead with the program. If you got a passing mark, you have enough knowledge to move forward, as far as your university is concerned.

But if you are unclear on the concepts and think even the 59% was some sort of miracle, then go back and retake it. Later classes will build on the concepts of the introductory class, and you don't want to build a building on a shaky foundation. Forget what your friends say; it's better to spend a little extra time and money at the start, then to flunk out entirely. 

I suppose it also depends on what you are studying. If accounting, you'll definitely need a good grasp of the introductory concepts; if general business, and this is your only planned accounting class, then you can give it a miss.
