It may take a few minutes for all the files to be added (depends how much music you have). A 'Quick Appearance Setup' window will open, select 'Album List + Properties'. The pay-off however is worth it you will soon learn how awesome foobar actually is!
This tutorial will take 20 minutes+ to complete, think of it as a cool project. It is unlike other media players that will work out the box. They best way to explain foobar's possibilities is with a demonstration of my own foobar set up. This thread will hopefully introduce you to many of the basics.
The learning curve is pretty much like a brick wall. The problem is that it is fucking difficult to learn how to use. It can be far more powerful than iTunes, Winamp and MediaMonkey if you know how to use it.
You can customize it in any way you want. Foobar2000 is an extremely customizable and lightweight media player.
