I never understood all those millions and millions of sold records that so many media always number like peanuts when they talk about this or that band...............Where comes this from? singles? cd's? vynils?.............
How can be a comment that wrong by claiming a band "big" relying it to sold records, because this can't be taken as the only factor. So, if you mean, great songs, many sold records, great tours, 30 years around with never a change of a member, great relationships with "fans", great activism, great family lovers, and great shitload of money owners..........then there's no doubt that U2 is the biggest band in the world
