A lot of rappers have music videos that are based in prisons. This might be the first music video ever shot and produced from inside a prison. The song is called "I'm On" by inmates in South Carolina inside what appears to be a prison cell. They sing "I'm on fire," but it's the song that's fire. The South Carolina Department of Corrections weren't as amused by it, however, as inmates should not have access to cell phones or the Internet. An investigation into the matter is currently underway. Watch the RTM reaction to this music video right here.
