Disklavier

Hi
Having recently purchased an upright piano I am keen to find some good piano 
files for rock, soul and blues.  I've searched the web and found some great 
files, particularly within this group, but I am looking for more 
contemporary pieces.  Beatles, Billy Joel, Bowie and Stones, would be a good 
start for Rock. Any Atlantic soul would be great.

Any help would be appreciated.
