Yes, NSYNC should reunited at the MTV Video Music Awards, because it would be very popular among women of Generation Y. Women of this era grew up listening to NSYNC, and they would be happy to have a chance to hear them again. It would be very nostalgic, and with publicity, it would get big ratings.
An NYSYNC reuinion is not a new subject. They have reunited in the past and are getting older now. I do not see a need for them to reunite at the MTV Video Music Awards. It is time for new groups to take the lead not dig up the older groups.
