Now I am not a U2 fan at all, and I've never listened to their stuff before.However, I heard Vertigo and I LOVED it. So what did I do? I went out and bought the CD with a giftcard I got for christmas.Yeah that was a mistake. Vertigo is a great song, but I hated the rest of them. I was hoping the rest of the CD would be as upbeat and as powerful as Vertigo, but it was all soft slower calmer music, and I didn't like it at all.
