Grammy-nominated rapper B.o.B. performed his song "Airplanes" on a Delta airlines P.A. system. Now, cute as seeing this on Delta's official YouTube channel is, how annoying would it be to be forced to listen to B.o.B. warbling along to an MP3 of his own song, through a tinny airplane sound system? Can't we all just agree to sit in tense, angry silence when flying the friendly skies?

Celebrity intrusions into daily life: How much is too much? Whereas getting interrupted by someone famous for interrupting others (like Kanye West!) is annoying in a cool way, I am of the opinion that B.o.B. interrupting your mid-air serenity is just plain annoying. [YouTube via RapRadar]
