The second side takes a turn. There are two disco/pop songs, a ballad and one that sounds more like the future. I Feel Love is the one that stands out the most. It uses synthesized sounds, something that wasn't heard much before. The song became an international hit, reaching #6 on the Billboard Hot 100 and was Donna Summer's first number one single in the United Kingdom.
The music of I Remember Yesterday was key to the growth of disco and other genres that came later. The repetitive vocal of Donna Summer in the background helped the song be heard around the world. The album was certified gold in the United States and reached #3 in the United Kingdom, her best position up to that point.
