Yamaha PSR-530 - Always piano backing track

I had this Yamaha PSR-530 as a beginner keyboard since 1998 and at that time I was blown away by its features esp this 2 sets of demo (internal and external/cartridge). This song was the first instrumental song I leanred to play by ear. I recorded this by lining my PSR-530 into my Korg Kross 1 audio in and recording the playback on the kross audio recorder. I made isolated tracks, a piano backing track, and a piano-only recording. I plan to do a cover of this using a better sounding piano soon (Addictive keys).
