It's one of my favorite albums. For me, they could only go down from there.
In the 2000's...
Three albums, 26 million records, 15 Grammys, 3 ginormous tours, including the 1st and 5th top grossing tours of all time.
Yep, U2 was still easily the biggest band in the world in the 2000's. You might find someone that sold a few more albums, but other than the Stones, you won't find anyone that could also sell concert tickets on the same level.
