Riding the high of his ABBA cover “Slipping Through My Fingers,” which amassed over 5 million streams on Spotify, Declan McKenna makes a comeback with his new album “What Happened to the Beach?” released Feb. 9. The cover is still only a fraction of streams compared to his most popular song, “Brazil,” which has over 400 million streams. The British singer/songwriter has accumulated 6.8 million listeners on Spotify since 2014, releasing two albums and 22 singles in the meantime.
