Pro Free, open source, and cross-platform
VLC is licensed under the CC-SA v3.0+ and available on Windows, OSX, and Linux with source code available here.

Pro Simple to setup and use
VLC is an incredibly robust application but very simple on the surface. It makes playing music simple, yet still manages to give the user all the tools he/she wants in a music player.
Pro Very versatile and easy to use
Pro Doesn't require additional codecs
Everything VLC needs to play media files is contained within which means no outside codecs are needed. This makes it one of the most hassle-free music players as it can play virtually anything as soon as it's installed.
Pro Tons of advanced settings
Besides basic configurations, video player has an extensive amount of adjustable settings.
Pro Doesn't manage your music library for you
You organize your music into folders any way you want. Want to play an album? Drag and drop. No tags, no confusion, no fluff. Easy.
Pro Can be almost completely keyboard-driven
VLC includes keyboard shortcuts for most actions. The video player can be controlled with simple and customizable keyboard commands.
Pro Surprisingly Lightest on Resources
Yes. Lightest. Even better than the ones known to be light. Both when playing music, only a single song or when playing a video. Either in terms of Ram and Cpu. Compared with almost all, including the ones from Windows like mpc-hc .. or light ones from Linux like Alsa Player, Audacious, SmPlayer .
Pro Can play every format video available (as of 2017)
Pro Supports a GUI interface and an ncurses terminal interface
Pro Can easily stream music across your home network from any device on the network
Using sftp/ssh music (and videos) can be streamed from any server on the network to any device running VLC. VLC can also be used as a webcam for streaming and snapshots. Amazing all in one package
Pro Large amount of extensions
VLC has a large amount of extensions.
Pro Super intuitive way of organizing and browsing albums and artists
You can view all the albums you have in one long list. Clicking on one of them will bring a popup at the bottom of the screen where you will see a list of all the songs on that album.
Pro Works fast and reliably
Pro Super flexible layout
The latest version has a good full-screen layout and is very responsive. Goes very smoothly from full screen to minimal player (also being a GTK+ app).
Pro Integrates with the MPRIS sound menu
This applies for most players in the "Linux world", but not for all. Therefore I consider it worth mentioning.
Pro Huge development
There is constant improvements, librem and gnome3 is possibly the future.

Pro Cloud music
Lollypop allow you to play music from the web (iTunes charts and search from Spotify).
Pro Integrates well with many desktop environments
One example being the conditional use of client side decorations (a.k.a. header bars) depending on the currently active desktop environment.
Pro Good party mode
Pro Clean, light and works very well.
The only one that can play a lot of files without to stop.
Pro Queue option lets you change what's playing on the fly
You can add songs to a queue, and then re-order or remove songs as you please. It works similarly to a temporary playlist.
Pro Online radio integration
The newest version features a nice interface for adding, browsing, and playing online radio stations. This gives you access to more music than you would normally have, which can help expand your music library for free.
Cons

Con Not really meant to be a music player
VLC is made to be a video player. Therefore, it won't carry out actions such as managing your music library.
Con Lacks libraries and advanced music player features
VLC is a media player first and foremost. There is no library management (aside from playlists), limited usage of tags, and no rating system. VLC is best at playing a file directly from a folder, but falls behind when it comes to helping you manage or find good songs in your music library.
Con Absence of personalization
VLC Player has only one basic interface in white or black, and overall personalization opportunities are quite narrow. Unfortunately, you're pretty much stuck to the default look.
Con Contains some insignificant but irritating flaws
Despite all keyboard shortcuts, the width of the picture can't be controlled by trackpad. Besides that, the VLC start-up window doesn’t open at the same place or the same width at which it was previously closed.
Con GTK App
Its a GTK app so integration in other desktops is terrible it also uses GNOMEs ClientSideDecorations so it will break many window managers.
Con No equalizer
Lollypop still does not have an equalizer.
Con Good party mode
Con No In-App Volume Control (0.9.242)
It has no in-app volume control, it has to be managed through system 'Sound control/Applications'

Con Requires a well organized music collection
Lollypop will be a pain to use if music is badly tagged. The setup is a one time thing, but it can be a pain to organize a large library.
