I think U2 should not be so hung up on commercial success and focus on the creative innovation they have become famous for. Commercial success has always followed when they create a great record, whether or not they think they have 4 hit singles on hand. They are game changers and with the state of the music industry/radio/music as a whole, they need to be the ones who change the game again. They did so in the 90s when they added electronic elements to their music, they did so in 2000 when they brought the idea of a rock band to the fore again and they did so with No Line on the Horizon by adding new elements to their songs. Think about it, when they brought back the idea of four guys in a band playing rock music in 2000, so many great bands and an entirely new movement of alternative rock bands like Franz Ferdinand, Coldplay, Arctic Monkeys, etc ensued. They are innovative leaders and have been for the past 30 years. I'd like to see them do it again, not just for the fans, but for the music world as a whole. If they do successfully create an innovative new record, new fans will be there, relevance will be there, and commercial success will be there. They sure grabbed my attention when I was just 11 years old watching the Super Bowl here in the U.S. back in 2002, never having heard of them before. There's no reason they can't have that effect on some young fans today. The rest falls into place from there.
