Lopster, a GTK+ file sharing client using the OpenNap protocol (which was built after the original Napster (which has nothing to do with today&#x27;s Napster) protocol)<p>You could download songs in 320kbps mp3 quality, you actually owned the tracks.<p>You could discover home-made remixes of completely unknown artists, which could happen to be truly amazing, and which then got lost forever after the downfall of the OpenNap servers.<p>You had an insta-search feature where you typed something in a search box, and the track list actually <i>filtered immediately</i>.<p>I miss all of this and I would pay so much money (even monthly) if something like that came up again.<p>Yes, it was illegal, and you have streaming services like Deezer and Spotify today, but try searching for Adele. There&#x27;s no point if you have to have 2-3 sources to listen to your favourite music. The movie industry is repeating the same fragmentation faults of the music industry. There&#x27;s still no legal way to stream or download your favourite music and movies.<p>You have music communities like Soundcloud, but artists need to pay money to make their work public (laughably unaffordable if you&#x27;re, say, in Romania) and the sheer amount of work went forever extinct, just like what happened to Grooveshark.<p>You could search your library, and the library would filter your results <i>instantly</i> by the letter you&#x27;ve just typed. This is impossible with today&#x27;s SPA platforms. Not a single competitor does sub strig filtering, and by the time your AJAX request hits the server, you&#x27;re already 20ms over the time the results would have been shown in Lopster.<p>There was a golden time when those Napszter clones were alive, anyone remembering WinMX? I&#x27;m delighted Soulseek survived until today, i&#x27;ll see what&#x27;s left from the legacy.
