Hit songs like ‘Bad Romance’, ‘Do not Stop Believing’ or ‘California Gurls’ are the top songs that we cannot get out of our heads once we listen to them.

Psychologists initiated a series of studies in order to discover a logical explanation why certain lyrics persist in the most obsessive way in our heads, writes The Washington Post.

‘There are certain parts of the melody from a song that remain etched in your mind and they replay over and over again.’, says psychologist Kelly Jakubowski, the author of a study published in the journal ‘Psychology of Aesthetics, Creativity, and the Arts’.

After an analysis, based on an online survey Kelly Jakubowski suggest that songs sung in a faster tempo, with few interruptions, are those who tend to persist in our memory, just like the following verse from the song ‘Bad Romance’ by Lady Gaga: ‘Gaga ooh-la-la / Want your bad romance.’

Jakubowski, who conducted the research while she was working at Goldsmiths University in London, says this is the first study who deals extensively with this issue. The results confirm that the songs are given to radio and the tempo has a big contribution in this context: ‘Once you listen to a very rhythmic song you get with it stuck in your mind. It’s very hard to get rid of it.’

Such songs tend to be simple, familiar melodic structures. For instance: ‘Twinkle, Twinkle Little Star’ starts slowly, gently and then gradually climbs the tone.
