Pros
Pro Streamlined player not weighed down by unnecessary options
Audacious is a classic music player at heart that has not felt the need to weigh itself down with an assortment of unnecessary options. Advanced functionality can be attained through plugins available from within the program.
Pro Tons of plugins
Pro Lightweight
My audacious uses only 18.5 MB of RAM. It has a Winamp visualization style that's very minimized and convenient.
Pro Support for Winamp themes
Audacious can switch from its GTK interface to one that matches the looks of the famous Winamp player. What's even better is that this interface supports any Winamp themes, which allows for more options.
Pro Folder oriented player, but able to play any music container and highly configurable
Lets you play, delete and even change metadata of your music files.
Pro The easiest player for multiple types of files
It plays dts, aac multichannel, etc.
Pro Compatibility with most media formats
It's able to reproduce most of media formats without external plugins.
Pro Needs no additional codecs
Everything MPV needs to play media files is contained within which means no outside codecs are needed.
Pro Integrates with streaming services
When used with youtube-dl.
Pro Minimal interface
Click to open files and get Video with sound (and passthrough of codecs like DTS etc) for a perfect cinema experience. Works okay for many files.
Default window is not much more than a title bar - and if you drag/resize the window it resizes the video and leaves no empty areas. There is no visible control or display unless you use mouse/keyboard over the window.
This is the best player to use unless you're going for a media center (then use MPV based Plex Media Player to display and play the Plex Server library).
Pro Up to date
Always up to date, rapid development.
Pro Extremely responsive
Pro Caches livestreams
Intelligently caches livestreams and enables jumping within the cached stream.
Pro Fast
Cons
Con No manual sorting fields
There is no option to add one's own categories to the sorting fields.
Con Updates are not very frequent
Con No bit perfect output past 24bit
Audiophiles require this, and while most users might not notice a difference, audiophiles will appreciate the improved audio quality.
Con Buggy
For example when using Visual Studio Code and Audacious you get flicked out to the gnome login screen.
Con Minimal theme support
Con Lack of a typical GUI can be jarring to some
The minimal interface comes at the cost of beginner-friendliness. You need to know keyboard shortcuts by heart, settings are set in text files, right-clicking won't bring up a menu, etc.
