Participants were then asked to identify the song, if possible (title, artist, or lyrics). Next, participants were shown a multiple choice display with four song titles, selected a song title, and were given visual feedback (correct: selected option turned green and a checkmark appeared next to the title; incorrect: selected option turned red and an x appeared next to the title.)\nSong stimuli are taken from Kostic and Cleary (2009): https://supp.apa.org/psycarticles/supplemental/a0014584/a0014584_supp.html\nAn audio file with a reconstruction of what each participant heard throughout the experiment can be found in /derivatives.
