Not sure about Offspring, but pretty sure 40something Blink 182 did this summer with Bored To Death. Remember being shocked that a 'rock band' did so well. It's been awhile since the old guard (u2, coldplay, oasis, foo fighters, green day, etc) made a dent like that
U2 seems to be a special case. They just don't... fit.
Blink-182 and Greenday are still viewed as "youthful" because of the type of adolescent, pop-punk they play. Foo Fighters, while I think are dreadfully boring, get decent play because they fit the straight alt-rock category. And Coldplay has mastered the crossover of alternative, rock, pop, adult contemporary mix, which gets them consistently strong airplay no matter how far their music stumbles down a path of mediocrity.
U2 is not rock enough to be on straight rock stations. They aren't viewed as alternative enough to be on alternative stations, they definitely aren't on pop stations, and if they do anything other than EBW / SFS type songs, they won't get on adult contemporary stations.
They could have gone the Radiohead route and started putting out more experimental and daring material that would have thrilled their core fans, and maybe brought in some new ones that were intrigued and respected that approach. But they still swing for the mainstream fences, and have now pretty much burned that bridge.
I really like TBT. It's crazy catchy and not as sappy/middle of the road type thing as SFS. I can see it doing pretty well adult contemp and adult alternative charts. But thats about it. might crack the Top 100 Billboard pop charts if it gets enough initial downloads and streams.
