What do U2 sing about?

Here's some what I think are interesting articles' that I wrote which attempt to pull together some of the common themes and concepts in the songs that U2 have written.

It's clear Bono has some key areas of interest, America, love, MLK, Elvis and of course, religion and this has been well reflected in U2's number one albums.

• All you need is U2 Love Songs - As it sounds, Bono's all loved up.
• Atomic Bombs - How do you dismantle an atomic bomb?*
• Bible References by U2 - U2 question and quarell about religion.
• Elvis was the King - Bono often refers to Elvis in his lyrics.
• Hello, I'm Johnny Cash - And then there was U2's love of the Man in Black
• How many number ones has U2 had? - More than most bands for sure
• Jesus, Yahweh and The Good Book - What does god want with U2. 
• Mothers and Fathers - Bono often writes about his experinces with his parents
• Name Droppers - Bono often name drops celebritities in his songs - and reveals his love of Michael Jackson
• Outside is America - Yes, America is a superpower and Bono noticed it.

* With love.
