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.
