May i just call bull shit on anyone who says gaga started the whole dance music thing im sure other artists were doing it before her an example britney spears with blackout it came out a year before gaga's the fame but yeah i like both but people really need to stop comparing everyone to gaga i love her and all but jeez As for the J.Lo song its hot cant wait for it to come out so i can dance to some J.Lo and Brit Brit at the same time :D
