Background music - a staple of students cramming for exams the world over - interferes with concentration, research shows.
Students who listened to their tunes while trying to memorise a list of letters fared worse than those who worked in silence, the British study found.
Even songs from their favourite bands proved more of a hindrance than a help.
Researchers from the University of Wales Institute, Cardiff, tasked 25 students with memorising lists of consonants.
Some were shown the letters while sitting in silence, others while listening to music by their favourite bands or by groups they had a strong aversion to.
Listening to music - including tunes that they liked - hampered their recall, the journal Applied Cognitive Psychology reports.
This shows that listening to music, regardless of one's opinion to it, impairs the ability to memorise information in a set order, said researcher Dr Nick Perham.
The students were also tested while listening to a voice simply repeating the number three over and over again and while listening to a voice saying random numbers - something known as a changing-state sound.
Although the random numbers proved a distraction, the repetition of the number three didn't.
This suggests that it is not peace and quiet that is important when studying - but lack of change in any background noise.
