Collaborations between country and pop artists became even more popularized during this decade, as well. In October 2019, country duo Dan + Shay released a joint single with pop singer-songwriter Justin Bieber, "10,000 Hours", which went to number one on both the Billboard Hot Country Songs and Country Airplay charts. In April 2020, country singer-singwriter Kelsea Ballerini released "The Other Girl" as a joint single with pop singer Halsey from her third studio album "kelsea". The single peaked within the top twenty of both the Hot Country Songs and U.S. Adult Top 40 charts. At the February 2020 Country Radio Seminar, there was discussion on the increase in fan attention to pop and country collaborations, in addition to an increase in the use of streaming services.
