I get the feeling that most of us hardhardhardcore U2 fans don't have much of a problem playing songs repeatedly for great periods of time. I think, though, that most really serious fans of other artists are pretty much the same way; I think that, at the same time, more casual music (or radio, I should perhaps say) fans are just the same way.
I wonder, though, how many people are like those of us on this particular thread....?
I've gone through some very, very unspeakably bad times, over the last eleven months or so, and I've relied on U2 even more than I did in the past, which I previously would have thought impossible...Springsteen, too. ...Actually, about a million other artists, as well...!
That said, this summer I listened to "Bad" for SEVEN HOURS STRAIGHT one day in July when I really needed some help. It was...yeah...
I still love it.
