Helium Music Manager
Helium Music Manager is a fantastic free media organizer and player will help you tame even the largest, most unruly music library.
Helium has everything you need to tag, sort and arrange your tracks, as well as a superb built-in player with excellent sort and search functions to help you find exactly what you want to listen to.
Why you need it
Helium looks great, and is highly customizable with collapsible panes showing information about your collection and the current track. You can add tags to songs while they're playing, see biographies and lyrics, and check out similar artists. There are even charts showing the years the songs in your collection were recorded and released.
If you own an iOS device, you can get even more out of Helium Music Manager with the Helium Streamer and Helium Remote mobile apps, which do exactly what their names suggest, letting you stream music from your Helium library to your device, and use it to control the desktop app.
