According to Wikipedia, Bon Jovi is a lot better than U2, please allow me to laugh out loud, very loud. Bon Jovi sold like 4/5 in the US, so to me it's not a world artist, it's a US one. Same for a lot of them. Same when they are just sellin in India or europe.
Like one of you said previously, the title of "Biggest Band in the world" is defined not only by the album sales, but also by Live performance, live tickets sales, etc.... When we look at that, U2 is the biggest band right now. The Rolling Stones would be if they were still making good music, but...
Who is seriously filling up 3 Stadium of 70'000 in Buenos Aires, London, Paris, New York, Sidney and Tokyo, Warsaw, Mexico, etc.... ??? I only see 2 bands, U2 and Stones.
The others are individuals like Madonna, but she just played Paris 2 nights, well, the second concert wasn't sold out. U2 played 2 sold out concerts "au Stade de France" 80'000 people each night....
The only thing that annoys me a bit is that U2 isn't seen as "legend" when I talk to "normal" non-fan people. They are just good, but no legend. What's missing I don't know. But Rolling Stones are legend, Jackson is a legend, Beattles, Pink Floyd, The Who's, etc.... Is it because they are still more relevant than ever?
