I am guessing there will also be a dearth of new albums this year as studio collaboration is hit hard, but a lot of artists will be recording stuff at home and there will be a rush to the studio next year with a lot of new theme music.
Also, as dreadful a correlation as this is, there is a correlation between sharp economic downturns and great music. People take out their rage in music, and often that means great new movements like Punk, grunge, industrial, etc., come from recessions.
