I loved WinAmp
... In 2000-2005 Nicky.
Also VLC is still great... For pirated movies that won't play on Plex because of bad encoding.
I agree with the general opinion that it's time for you to get Spotify.
However, if you MUST keep using your old MP3 collection, you want an application called "MusicBee". VLC has literally never been good for organising audio.
