You will only get the password when they reach 5,000 followers and at the moment, their followers are 2,540 and they need another 2,460 followers, which they should get in another couple of days.
They will change the password randomly but what is amazing, is there are so amazingly-exclusive songs that will be leaked and this is to stop trouble from the record labels. And wouldnt you like to be a part of a small, exclusive society?
