The show centers around music and fashion. As each artist performed, models (both male and female) paraded around on the runways. However, they were dressed somewhat "normal" and not in attire you see in a lot of shows. You know: Clothes you never see anybody wearing anywhere. Most of the clothes looked like what you'd see on average people.
The band called Magic! did a really good job on their song called "Rude". I found it odd to see a person in the audience wearing a black t-shirt with Charles Manson's face on the front. Other standout performances included The Band Perry, Rita Ora (who was looking hot!) and - to my surprise - Nicki Minaj.
Interestingly, Jennifer Lopez did a new song and deliberately showed off her famous butt. When Minaj hit the stage, she also made it a point to shake her derriere toward the audience. The cameras panned to Lopez (who had since moved to the audience) on more than one occasion and I would best describe her expression as "stoic".
Justin Bieber introduced an act but not before stripping down to his skivvies. He acted like bit of a douche.
Between performances there were snippets with fashion designers and they were fairly brief but somewhat interesting.
Bottom line: If you like a wide variety of music and lots of cleavage, I'd recommend it. But, I probably couldn't sit through it again.
