I'll bet for every keyboard owner that plays a contemporary "Pop" style, there are 5 keyboard owners that play a cha cha...
These styles are not outdated. There will always be a cha cha, rhumba, tango, waltz, and swing..We can't be without these for the sake of more Pop styles[even hip hop and new age]...Sure , go and add these , but not at the expense of "real' styles..


Same thing with the "dated" sounds[tones]...A good piano sounds just like it did 20 years ago...sax, the same...Has a flute changed?..what about choirs? The mighty B3?

I will be happy to keep my outdated sounds..and my ballroom styles..
