I expect that this has already been said, but people who flick around radio channels every time something comes on that they don't like. Particularly in the car, or another situation where you basically want something on in the background. Pick a station that doesn't annoy you much and stick with it. If they play a tune you don't like, lump it for four minutes and wait for the next one. If they keep playing tunes you don't like, pick another station and stick with that. DON'T put on one station, listen to a tune, decide that you don't like the next tune, skip around five more stations, flick back to the first station (tune is still playing) flick around a bit more, finally settle on another station, listen to a tune, get annoyed with the DJ, flick around some more, repeat...
