Even with newbies like The Wanted, Psy, and Carly Rae Jepsen performing at the AMAs, tonight's 40th anniversary of the award show has seemed like a blast from the past. The red carpet was visited by a variety of popular musicians from years past, from Gloria Estefan to 50 Cent, Cyndi Lauper to Linkin Park, Brandy to Usher, and No Doubt to Backstreet Boys. Many of these pop, rap, and rock stars have a history of attending the AMAs, so let's take a look at their presence at tonight's show compared to back in the day!
