The "Dreaming of You" singer's father, Abraham Quintanilla, said the song was never recorded professionally, but they found a recording of Selena rehearsing the track and decided to release it, reported Entertainment Weekly.
"The reason we never released it as one of her songs is because it's not up to par as far as sound is concerned, but years later my son AB recorded it with the Kumbia Kings.
"We thought that the fans would enjoy it even though it's not a professional recording," he said.
