Grooveshark was founded in 2006 by college students as a paid downloadable music service but later transitioned to being a free streaming music platform accessible through their website or applications. It allowed users to search, stream, and create playlists of music without having to download songs. However, Grooveshark faced major lawsuits over pre-1972 recordings and legal issues led to its services being removed from platforms like Google, Apple, and Facebook.
