Final answer:
The statement is true. Both single-song sales and digital album sales are popular in the music industry.
Step-by-step explanation:
The statement “While single-song sales remain popular, digital album sales also are picking up” is true.
In the music industry, single-song sales have been popular for many years and continue to be popular due to the ability to purchase individual songs online through platforms like iTunes or Amazon. However, digital album sales have also been increasing in recent years.
Artists and record labels often release their music in both formats - single songs and full albums - to cater to different consumer preferences. While some people prefer to buy individual songs, others prefer to purchase entire albums to enjoy a cohesive collection of music from their favorite artists.
