Rabid Neurosis (RNS) was an MP3 warez release organization which was founded in 1996, following in the footsteps of Compress 'Da Audio (CDA), the first MP3 piracy group. In 1999, the group claimed to have released over 6,000 titles a year. RNS occasionally used the tagline "Rabid Neurosis - Spread The Epidemic." RNS were best known for releasing highly anticipated albums by hip hop, pop, rock and dance artists weeks and sometimes months before their official release date. RNS is known to have greatly contributed to the mp3 scene. After their group was mentioned in an MTV News article about the early leak of the Eminem album Encore, RNS stopped including their initials in filenames and ID3 tags.
