Jennifer Lopez premiered her new single 'Dance Again' featuring Pitbull on American Idol last week which is supposedly the lead single off her upcoming greatest hits album.  The song is another great dance song that is in much the same vein as her previous album LOVE?  It also features a great breakdown where J-Lo struts her stuff, and some great raps from the incomparable Pitbull.  The video, however, left me very underwhelmed.  It just seemed very cheap and tacky to me.  All the upside down effects were low quality, and when Jennifer is covered in body paint and is all sparkly it looks corny.  This is not the level of quality she should be putting out there.  Hopefully we'll get something better in the future.  A performance on Idol maybe?
