Lady Gaga's queen of the earworm.
BAD Romance by Lady Gaga is the most catchy earworm with Kylie Minogue's aptly-named Can't Get You Out Of My Head in second place, according to academic research.
Dr Kelly Jakubowski has studied the phenomenon and identified what makes a song more catchy than the average pop tune.
Researchers asked 3,000 people for their most frequent earworm and analysed what set them apart from equally successful songs that did not have the sticky factor.
The Durham University academic found they tend to have: ? A faster tempo; ? A simple melodic structure, like nursery rhymes which rise and fall in pitch; ? An unusual interval structure in the song, like unexpected leaps or more repeated notes than the listener expects.
