Along with Dave's suggestion about using performer's gig disks for tying specific song names to specific keyboard setups (in your case: styles), you may also want to take a look at the Music Finder Databases (MFD) in that same general area. In particular is Joe Waters' Master Music Finder Data Base that is based on entries from 50 different fakebooks. On that page, if you scroll down to about mid-page, you will find a download list for specific models all the way from the PSR-2100 up through the S950 and Tyros 5 (right down your alley). BUT . . . . while you are there, also take a look at the MFD's that have been submitted by some of our most prolific performers. That list has to represent many hundreds of year's of some of the best collective experience you could ever hope to find anywhere.
Best of luck with your search!
