I'm sure most people have a backing track of this song in some form but...

Here is a backing track of "So what" (it's label as Impressions but it's definetly closer to So What). I just founded in my Itunes and it's a pretty long back track.

 

The sound quality is really good but the problem is there is no count in so good luck with that.
