I'm not sure where you work or what your legal background is, but this is completely off from my experience.
In-house entertainment companies couldn't give to shits about where you went to undergrad and usually don't give half a shit about where you went to law school. They do care about where you worked prior to applying.
All the execs I worked with were from various law schools, but the thing they had in common was large law firm experience.
The key to getting in-house is not about your law school specialty ranking because law school specialty rankings are a joke. There is no law school that has an entertainment law program that is so world-renown that Sony, Universal, Paramount, etc., are scooping up 2Ls during OCI.
**Newsflash** in-house companies don't recruit law students they recruit lawyers.
So, OP trying to find a school in the south east that is the best for entertainment law is completely pointless. OP needs to go to a good school and try and get a job at a law firm and then after 2-3 years at least of law firm experience start looking at positions in-house, hopefully doing entertainment. Working at a firm that does soft IP work or has an actual entertainment practice would definitely be helpful but is not necessary. If OP wants to say in the south east and wants to work in entertainment then trying to get into the Nashville area is a good idea because, despite what people may think, Nashville is HUGE in the music business, and not just country music. Nashville is a great place to get into the music business. LA is the place to be for movies, NY and Chicago are great for theater. Fortunately, these cities also correspond to having a large number of law firms. It almost goes without saying, that if one can attend HYS then one should attend HYS, because chances are that whatever you want to do with your life you can do it with a law degree from HYS.
But if you have very specific goals such as, entertainment law, then in addition to trying to get into HYS, the real answer is to make a good financial decision about the best law schools you have been accepted to. Once in law school it's going to be important to get some experience in the business. This can be accomplished through semester or summer internships. All major entertainment companies offer such internships. There are also numerous smaller entities within the entertainment business that will allow you to work in the mail room--in the entertainment business this is actually valid work. The mailrooms of most of the major talent agencies are filled with JDs and MBAs trying to work their way up to talent agent. There are law grads of schools of every tier trying to become talent agents and did not go the law firm route. Most talent agents don't even have a graduate degree and trying to become a talent agent purely based on prestige of your law school isn't going to work well. It won't really matter that they went to HYS or Tier 4 school if the company is going to start everyone in the mail room and make them work their way up. A degree from a certain law school is not going to help in a business where you really just have to know people and network (with the exception that your school and your alumni network may in fact provide you with the "who you know" to move up).
Since the best way to get a job at an in-house entertainment company, which is what most people think about when they say they want to work in entertainment, is to get to a large firm, then real question is, "what's the best school to get a law firm job?" Which is talked about on 99% of the threads on this site.
This is a pretty good breakdown of reality (and of why Applying_Late is a clueless 0L).
