Music videos can help boost the success of songs by increasing views, publicity, sales and downloads. Sinead O'Connor's cover of "Nothing Compares 2 U" became more successful than Prince's original version due to her iconic music video, which featured close-ups of her crying and walking in a garden in black clothing. The video won several awards despite its gloomy and repetitive nature. Similarly, A-ha's "Take On Me" gained popularity in the US and UK through its innovative music video featuring animated sequences, which was groundbreaking at the time and helped expose the song on MTV.
