I actually prefer VLC to foobar2000. However, I still prefer classic Winamp to to all other music players, and I wish I could get Apple Music work in the same interface. I like 100% of the classic Winamp player UI/UX.
- I like the separate player, playlist, EQ windows.
- I like that I can re-arrange the windows, and resize the playlist separately.
- I like that the main player has a little EQ built in.
- I like the layout of the main window. It's perfect.
- I like the layout of the playlist window, it's also perfect. I can add "directories", "albums", etc. and again, I can resize the window.
- I like the skins. I like the classic skin, but I also love the Sonicated skin. I still have it on my Windows laptop.
- Conversely, I really dislike the "native" UI elements.
- I like that lack of rounded corners on the classic Winamp windows, such that when windows stick together, they appear as whole, and I can drag them around as one.
Mostly, it's a bunch of seemingly small and aesthetic things, but if a player doesn't have those things, I might as well just use iTunes.
Winamp was synonymous with m3u playlists, how well does VLC handle those?
Ah, fond memories of cron jobs generating m3u playlists for me ...
Apple has MusicKit now. In theory you can build whatever (Mac or iOS) app skin you want on your Apple Music subscription.
