From 1998-2001 Napster was a groundbreaking free music file-sharing service that was responsible for the digital music industry. It preceded iTunes and spotify and shook up the music industry at the time. After a long legal battle it was eventually shutdown.
Rhapsody, who now owns the Napster name has announced that it will re-brand itself as Napster and apparently will offer the same style and feel as Rhapsody but this time it will have the retro vibe of Napster and will be legal. Rhapsody has promised current users will not be loosing their playlists or accounts.
The name change reflects a marketing strategy to capitalize on the trend of throwback that has been present in television and movies.
