Light, yet powerful music manager and player
When you think about music managers, iTunes is probably the first option that comes to mind. But that doesn't mean you should discount the alternatives.
Tuniac is one such alternative: a light and fast music manager that doubles as an audio player. While it doesn't feature as many tools and options as other managers, Tuniac is a perfectly valid tool if all you need is a simple, unobtrusive manager with playback capabilities.
Tuniac creates a library with all your music and then lets you create as many playlists as you want. The program also includes a built-in search tool to browse your MP3, and supports the usage of plug-ins to show the song currently playing in Messenger and on your desktop as well.
In short, Tuniac is a handy music manager that doesn't hog resources as much as other similar tools, but which still lacks advanced tools like global hotkeys, a decent tag editor or some nice visual effects.
If you're looking for a simple app to manage and play your music, Tuniac is your program: light on resources and with a handy, minimalist interface.
