4-MusicBee (Windows)

In contrast to many of the music players that have tons of options, tweaks, and toggles, MusicBee starts you off with a super-lightweight but still customizable utility that you can load up from there pretty easily. A little effort gets you things like song lyrics, album art, artist info, and so on. You get a wealth of built-in skins and customization options to get you started, but none of them slow the player down or make it feel bloated or slow. MusicBee can also handle large libraries, podcasts, less-popular file types, CD ripping, and more. You can use it to organize your library, tag your songs, and download additional data about your tracks. It supports syncing to mobile devices as well, and much more, all in what's often described as a "deceptively simple interface." Many of you praised MusicBee specifically for being so deceptively simple: Out of the box it's fast and easy to use, and you won't spend a lot of time just getting it to work and play your music. However, the more time you sink into it and into exploring its plug-ins and added features, the more rewarding you'll find the app to be. Some of you noted it's a perfect replacement to show people still using iTunes or Windows Media Player what a lightweight and customizable player can be, others pointed out that even while other tools offer way more features, MusicBee is the perfect balance between features and usability. It's completely free.
