The maximum number of U2 songs that description could POSSIBLY apply to is MAYBE 3 or 4. I love the ENTIRE U2 catalog up THROUGH ATYCLB. Don't make inaccurate generalizations.
As for the original topic, saying that, in order to love a band, you must love ALL of their songs and records, that kind of mindset is similar to the mindset that some people have of 'My country, right or wrong'. Sometimes one of the most profound displays of love for your country can be the act of calling it out when it is wrong, and sometimes one of the most profound displays of love for any artist of any kind is calling it out when you believe they are performing at a level beneath what they are capable of.
