FLAC releases can optionally include M3U playlist files. Lossy audio: MP3 At the start of the MP3 scene in 1995, there was little organization or standardization. Between 1999–2004, the pre-dominantly used MP3 encoding quality was 192 kbit/s at 44.1 kHz, which was nominal for the hardware and software encoding available at the time. This improved as computers got faster and the LAME MP3 encoder developed into its later versions. Due to broad support in hardware devices, unauthorized audio material is usually released in MP3 files at VBR quality. In 2007, new rules put forth that it is recommended to encode all files with Lame 3.97, using the "-V2 --vbr-new" switch. Other formats such as AAC or Vorbis are currently not allowed. In 2009, new rules were introduced. Homemade releases are forbidden. Every release needs an ID3 v1.1 AND ID3 v2 tag. Extra material that is available on the source material is allowed to be released. Flash storage mediums are allowed as sources to accommodate some retail releases made exclusively in those formats. The early MP3 release groups, 1996–1997, were considered "lamers", bottom feeders. In 2000, the former leader of Rabid Neurosis, Al Capone, posted a letter to the scene on the RNS website, complaining how the mp3 scene became more like the warez scene during its first 4 years. Lossless audio: FLAC An early scene release came in 2004 when the group ARA released Metallica's fifth performance in Gothenburg as FLAC files. These lossless files can be bought on LiveMetallica.com, a service that allows fans to buy and download files of soundboard recordings. From 2007 on some early FLAC releases came from justice, a group that already used APE for lossless music the years before. That same year the Polish group BFPMP3 thought to start promoting the FLAC standard with some internal releases. Single purpose groups such as judge, FLACH or CDDA created only a handful of releases in the years before the first ruleset. On October 2, 2011, the scene introduced a FLAC category by releasing a first ruleset. Eight days later an updated revision was released. According to the documents, the ruleset was created to satisfy the long lasting audiophile's demand for a music scene of higher quality than LAME mpeg compression encoding and because space and bandwidth were able to accommodate more. To avoid previously made mistakes in the music scene, a group of elder sceners gathered
