Where I work, usually, nobody ever listens to music. But one night, when I was working overtime during the summer of 2010, someone was playing Hot n Cold, and someone else said "Do you know that the woman who sings that is really hot!" I was tempted to add that she's also a very talented singer and a very nice person, but resisted the temptation.
More recently, one of my colleagues (who is known for not being the brightest bulb in the circuit, and among other things, is known for his extreme lack of music knowledge) was listening to the radio, and A Moment Like This, by Kelly Clarkson, came on. Another coworker asked him who sings this, and he (incorrectly) said "Katy Perry." lol. That same day, Roar came on, and somebody else asked him who sings that, and he said "I think Katy Perry." He then referred to Russel Brand as "that jerk from London". I wonder why he thought Katy Perry sang A Moment Like This.
