Pros
Pro Functionality can be extended with components
Foobar200 has over a hundred components to choose from that add UI functionality, decoding support for various formats, etc.
Pro Plugins can be used to bypass Windows mixer to output a bit-exact signal
Through the use of a plugin (of which there are three popular ones), users can get bit-exact sound output straight to their DAC or soundcard. While not something every user will use, for audiophiles this is a pretty important feature.
Pro Random/Shuffle on an album basis.
I'm old enough to have a lot of music where whole albums are worth listening to. This is also essential when the composers created music where the flow from one song to the next is part of the art of the album. E.g. on Queen's ANight_at_the_Opera_, the first song -- Death_On_Two_Legs -- is a very hard rock song with very pissed off lyrics. The next is _Lazing_On_a_Sunday_Afternoon, which is a very lighthearted amusing song. The contrast is wonderful. Also many artists have one song flow into another and breaking them up by using random on a song basis really breaks the music. Plus shuffle prevents repeats until the entire playlist is done. If you want, you can select individual songs and the are shuffled as if they are the entire album. It's harder to describe than to do:
configure play mode to shuffle albums
If you're like me -- and I know I am:
add library to list
play
But you can be more selective:
select albums (or songs if you only like a few)
do {
play_the_shuffled_list(list);
if (mood("not in for the current"))
skip();
if (mood("change_the_list))
change_the_list(&list);
} while !shuffled_off("mortal_coil");
die("happy");
Cons
Con Outdated Plugins
Many, many plugins are outdated and not maintained for years, leading to stability issues with a lof of them. A rather complex SDK and missing sufficient documentation makes maintaining or creating new plugins unnecessarily hard.
Getting to that neat GUI setup you've seen somewhere is probably impossible because of that.
Con Locks files and folders, making it hard to manage them
Several parts of Foobar lock files and folders in a way that they cannot be file-managed (move/copy/rename/delete) easily in the program (and externally). With the waveform plugin it's even worse. Cannot delete a file until the waveform is fully scanned.
Con The previous button doesn't work in random playback
You are unable to go back to a song when using random playback.
