General info on U2 

It would be great to add a section of U2's characteristics that sets them apart from most bands. For example, I hear that they have always owned 100% of the rights to all of their music (instead of the record companies). Also, they rarely ever allow sampling of their songs and they are very careful with allowing their songs to be used in advertisements. If I have time I might see if I can find more concrete information, and I'll include it in the article.
