A woman who sued Beyonce Knowles claiming the singer illegally used her lyrics in the song Baby Boy has taken her case to a US appeal court.
Jennifer Armour claims Knowles, 26, took lyrics from her song, Got A Little Bit Of Love For You.
Her lawyer said the case, thrown out by a judge in Houston, Texas last year, should be heard by a jury.
Dana Kirk added an expert analysed the two songs and said the two were substantially similar.
But Ms Knowles' lawyer, Cynthia Arato, said the standard for copyright cases is what an ordinary person hears, not an expert's analysis.
The judge in last year's case ruled the two songs were "substantially dissimilar".
Ms Armour's song is slower and more melodic than Ms Knowles' hit.
"I do believe it was the heart of my song," she said after the hearing in Lubbock, Texas. "When I first heard it, it hit me."
The panel of judges did not issue a ruling on Wednesday.
