I like to hear and dance to 15 out of twenty i know ...and learn about the other five ...that way I get best of both worlds you
cant "really" dance to something you dont know....you can just adlib as it goes on...hey, ....nowt wrong in that , but many like to know where the breaks, the slides, the fast bits n' the slow bits are... only then are you really dancing to the tune........just my take
one other thought is that in packed dancefloors you would stay on the floor cos you could not get off lol...n' if yer did you lost your space....so many people danced to what they did not know or had never heard cos they were stuck there not wanting to give up that space you just made
