Pet peeve: when people claim they love a band and can only name one of their songs

Don't you love it when you're playing Zeppelin on guitar, and your friend asks you to play stairway to heaven cause they LOOOOOVVVVE Led Zeppelin, and that's the only Zeppelin song they know.
               By "love" i mean hate.
             

    Greetings fellow followers of bands that only had one famous song that people still know today, today i shall rant about the lack refinement in our musical culture-again. It is perfectly fine to not listen to a band and not respect them. It is perfectly alright to not listen to a band and respect them, but to not listen to a band and LOOOOOOVE them, only having heard that song of theirs that was popular in the 70's. People should commit to their band, the white stripes didn't only write seven nation army, and the song seven nation army is more than "OOOOH-OH-OH-OH-OH-OOOOOOH-OOOH" its a time out at a football game song. The point is, listen to a band before you "love them."
