Deleting music?

I cant delete all my music at once.. it only delete music one by one.... Kinda stupid when i have a shitload of musig that i want to replace or delete completly... 

Might be worth fixing .!!!!!! 

Can you tell me which web browser are you using? And the connection mode? Is there any error message when you try to delete them all but failed?

Does this happen when you try to delete other files?
