No seriously, this times lack talent IMO.
I completely agree. For me, most of the bands that are currently making good music were also doing so back in the '70s, '80s, and '90s as well. There are currently so few truly great artists out there that, for me to come up with any artists that I'd like to see perform a Bond title song within the next few years, I really would have to step outside of the box and think in terms of the types of artists that we're really not used to having perform the title tracks.
Based on "current" artists, my suggestions for future title song performers would be:
Maroon 5 featuring Rihanna (I loved their collaboration on "If I Never See Your Face Again", and a similar sound would work great for a Bond title track)
Def Leppard featuring Taylor Swift (Yes, it's a very odd combination there, but had Def Leppard not released "When Love and Hate Collide" over a decade ago, their collaboration on the song with Swift would have been, IMO, the perfect
title track for QUANTUM OF SOLACE. With that in mind, I'd be more than willing to have them take on an original title track)
P!nk (I like the current overall direction the title songs have been headed in, and I think that having a female artist perform a rock song would be a great move for BOND 23, and I think that P!nk would do a great job with it).
Joss Stone (An artist that is more in line with the traditional style of Bond title song. She's long been an artist that I'd like to have performing a title track.)
Duffy (For the same reasons as Joss Stone)
Lindsey Buckingham (Could deliver either a completely off-the-wall rock number for a more experimental title track, or could deliver a fantastic, but subdued acoustic number that could also work quite well)
