How am I supposed to know that?
My GUESS would be that PowerAmp is READING the music folder and MB is WRITING TO the music folder. But why are you addressing this to me? Seems to me you already got an answer from the guy who wrote the program.
Sorry I was just wondering and didn't know if you knew.
Just having conversation. Your speculation makes sense. Musicbee could be asking for read and write permissions. Perhaps Steven has some insight on it.
I'm using a Galaxy S21, Galaxy 9+, Galaxy S7, a Galaxy Tab S 8.4, Poweramp, and Musicbee.
