I want to know the answer to the following question:
Along with electronic pop, what type of music was the most successful in the 1980s?
All the background I'm provided with is that "Although dance-oriented, electronic pop and ballad-oriented rock dominated the 1980s, soft rock songs still enjoyed a mild success thanks to artists like Sheena Easton, Amy Grant, Lionel Richie, Christopher Cross, Dan Hill, Leo Sayer, Billy Ocean, Julio Iglesias, Bertie Higgins and Tommy Page.". Is that enough to answer the question?
