Hmmm....
1970s: Bruce Springsteen - Born to Run (yes, you've bludgeoned me into submission)
1980s: Pet Shop Boys - Actually
1990s: Blur - Parklife. Or The Prodigy - Music for the Jilted Generation.
2000s: Muse - Black Holes and Revelations. Or Girls Aloud - Tangled Up.
2010s: Something by Lady Gaga perhaps?
2020s: Maybe Taylor Swift. I'm not sure...
I'm much more of a singles person than an album person, so this is tricky for me. And now I've left out U2, which is just wrong (Achtung Baby would be my top choice for them).
