Chalk up another Foobar user.
What ultimately made me pick Foobar was firstly, because it can handle anything I throw at it, and secondly, because it was very easy to disable the library function and download of cover artwork and all that. I don't need a program to keep track of my music for me, I know where I've got it stored, I don't want my media players synced to all my USB sticks, what's on them changes all the time anyway, I certainly don't want a 400*400 picture of a cover of a CD. What's that even good for? I can create my own playlists and keep track of what's on my harddrive myself, what's more, I'm better at it than any program I've come across so far.
