MeleeFLACs X

MeleeFLACs X, originally called SmashFLACs from 1999 until 2001, was an Eirabourne, El Kadsre-based company established in Kozankyo, Minecraftia in 1999 and operated from 1999 until 2009, providing extended video game music tracks from various games. The channel was founded by the Kozankyo University couple of Katsuo Nishihara and Yumemi Kutaragi and was originally based in Kozankyo, Minecraftia before moving to Eirabourne, El Kadsre after the couple's graduation in 2002. The channel was a major success for Nishihara and his wife, causing them to rise to fame. At their peak, their channel was viewed more than 1 billion times and garnered more than 500,000 subscribers. It was also the 13th most-viewed channel on VidSpace.

On May 17, 2009, the El Kadsreian Ministry of Culture and Nintendo of El Kadsre shut down the channel after the founders were arrested and formally indicted for being an organization dedicated to piracy and copyright infringement, as many of the music tracks provided downloads to the songs in FLAC format, hence the name. The shutdown of the channel led to massive outrage among its fans, leading to the Minecraftia Day Internet Blackout, causing multiple websites to be defaced with SQL injection and servers downed by denial-of-service attacks by hackers who were fans of the channel.

In 2010, the channel was relaunched on YouTube as BrawlBRSTMs3 X, having been decimated multiple times before it was decimated by Nintendo in 2019. It is now known as Aacro Xtensions.
