This CD single "You don't know" brings one of the best remix of 1999, but the radio insists on playing the trash cd sinlge of Cher. Damn "You Don't Know" has this great voice of Cindy Lauper for me the best pop singer in the entire world and also the great sound and work of the guys who did this fantastic remix. Buy it, because you going to dance day and night. Cindy Lauper it is very mature and fantastic in this CD. Radio guys play this song sometimes and stop to insist only on cher and Madonna. Damn I am sick and tired of those 2 queens!!!!!!!!!!!!!!!!!!!!!!!!!!!!
