it’s lightweight and also has no library management

That's the point for me for Audacious. I don't want to dig through my entire 30+ GB music folder, create a massive index or whatever, load all that shit to memory every time I open the fucking program, just to play one album.

"Oh I want this album"> Drag it in
"Oh I want this discography" > drag it in

The only problem is no multi column tab view, and no drag into empty space/designated zone to create a new playlist.
