The really interesting thing to me is that "Ultra Violet" was named the most popular song on Achtung Baby. In 2007, it only had 10% of the vote. Then in 2010 it had 17%, but was still behind "One." And then this year, it got 20% of the vote and surpassed "One" and everything else on the album.
Gotta credit the 360 tour for that song's rise in popularity.
