Only works with two of my songs – Bass Booster Volume Power Amp Review

I don’t know if it’s the apps problem, my phones problem or if I’m doing something wrong, but all of the songs in my library are gray, and when you click on them they don’t do anything. Only two Billie Eilish songs worked. The text was black, and when I clicked on them they played and worked.
