LimeWire was the king of peer-to-peer music sharing in the early 2000s, hitting the scene in 2000 and running hard until it got shut down in 2010. If you were online back then, you probably remember firing up LimeWire 2.0 in 2001, then watching it get faster and cleaner through versions like 4.0 in 2004 and 5.0 in 2008, which finally had a sleeker interface and better search. It was the Wild West for downloading MP3s, movies, and random files—half the time you’d get the song you wanted, the other half you’d get a corrupted file or a virus. Still, for anyone growing up in that era, LimeWire was the gateway to building your first music library without spending a dime, and it defined a whole generation’s relationship with digital media.
