Someone once said foobar is great for two types of people; those wanting a ultra basic, fast, clutter free platform just to play music and those that want something more advanced and are able to put in the time and effort customise their foobar setup. I'm actually the former type.
My albums, hundreds of albums, are arranged in basic folder's on hard drives and that's how I play them. I don't need a massive playlist manager (I just listen to one album at a time), I don't bother with album art, lyrics, internet connections, streaming, fancy features. Actually, apart from using the asio4all and advanced control foobar plugins, I'm all done.
I'm fine with album art, but iTunes takes a long time getting things right, organizing small lists is fine, but if you have a lot of songs, its a pain.
Also, iTunes deleted my playlists a couple of times when I opened the player. The first time I rebuilt the playlist, the second time I didn't bother.
