Who's going to play the Super Bowl halftime show when classic rock legends die/quit?

Was a conversation I was having with my dad when we were talking about the Boss. Seriously, what happens when all the 50 and over bands hang em up? Here are the performers since 2002:

U2
Shania Twain/No Doubt/Sting
Janet Jackson/Justin Timberlake/Nelly/Kid Rock/P. Diddy
Paul McCartney
Rolling Stones
Prince
Tom Petty
Bruce Springsteen

Except for that '02-'04 span (and U2 ain't getting any younger), all those were people my parents love/grew up with. There's nothing wrong with that, and I see why - the NFL audience is older white people - but there is going to come a time real soon when those acts are going to retire.

And then what happens?

There are certain criteria that the Super Bowl halftime act of say 2015 must have:

• Friendly to whites. This is key as all the NFL big wigs are Caucasian stuffed shirts and cannot be offended by those "hip hop" acts or any musical acts that have released less than like 20 albums. I don't understand how Nelly and Kid Rock slipped through the cracks.
  
• Pop, rock or nothing. Maybe Opera or some lounge singing or something, but there is little wiggle room here. Sure, pop and rock are all encompassing, but they also eliminate a ton of possibilities.
• Controlability/predictability. Ever since the legendary Janet Jackson incident (which was probably the most memorable moment since U2's post-9/11 tribute), acts have to be as clean as possible. No crazy Axl Rose-types allowed.
  

With those in mind, here are my guesses.

Coldplay - 90%

The biggest no-brainer on the list. Their newest album really blew the mainstream doors open for them and that Apple ad doesn't hurt. Their whiteness level is huge, they are friendly-looking (and Chris Martin is an activist to boot!) and perform big pop/rock anthems. Done and done.

Kanye West - 65%

West loses points for predictability as he may be one of the craziest dudes on the planet and giving him the Super Bowl stage may a terrible, terrible mistake. But he's the most white-friendly rapper alive and is arguably the biggest hip-hip act around.

Radiohead - 30%

They may be somewhat of a long-shot, but this year's Grammy's will help to expose to a whole new set of out-of-touch white people. I could totally picture them playing a halftime show when I have kids and me telling them how they were fucking badass they are.

Rihanna/Beyonce - 80%

A double-bill of these two would be a great idea. They make up for a slight lack of white-friendliness with hotness, which is the universal language. Both highly recognizable and safe. Once the censors lighten up about that whole Janet thing, they'll perform - and sooner rather than later.

The Jonas Brothers - 66%

The only reason they aren't closer to 100% is that their window is small. By this time next year, pre-teen girls could be obsessed with someone else. It's pretty much next Super Bowl or bust. There is a precedent for this, as NSync and New Kids have done it in the past.

Lil Wayne - 15%

In reality, this is a pretty big longshot. He is not white-friendly (tattoos!), his raps are fairly profane, and he is nipping at the heels of Kanye for craziest mainstream musician on the planet. But with the Grammy's coming up and the Couric interview (bowling!), along with tons of radio play and a huge 2008 album, he's got a chance.
