Have you found that you've never really fallen in love with iTunes or any of the other major media players? If so then you might find Jajuk a breath of fresh air.
Firstly, Jajuk is based on Java which I don't usually like but because the program does such a good organising job, it's worth tolerating the occasionally lags and sluggishness.
Jajuk is very flexible in that it can handle music in all sorts of formats including MP3, OGG Vorbis, AU, AIFF, WAV and SPEEX audio formats. The problem is that this is no simple organiser of music - it's very specialized and quite technical meaning that you'll spend a good few hours just getting to grips with its main features.
On the plus side, Jajuk is remarkably fast intuitive in the way it organises your music into different genres, bands and titles. I particularly liked the ambiance manager which allows you to make playlists based on genres of music to suit your moods. There's also a basic but functional DJ tool in Jajuk which includes a configurable crossfader for some super slick mixing and editing of your favorite tracks.
Jajuk is a very exciting alternative to iTunes although it's maybe a little too bloated with features for it's own good.
- Jajuk requires Java 1.6 to run A deep refresh will be proposed to you to take into account changes to tags and album covers if you upgrade from a pre-1.9 release. You can perform it manually from Devices view / right click / Force Refresh / Deep. [Windows or OSX in Web Start mode] The first startup will take a while (in the "Initial checkups" step), as the required mplayer executable is downloaded
