I am exploring Poweramp which seems to be an excellent music app.  My problem is that when I load a CD into the Music folder on my Nexus, I see one copy of the album when I open Library in Poweramp, but two copies of each song in the album.  The opposite happens if I open the Folders section of Poweramp -- I see two copies of the same album, but each has only one copy of each song in it.

How do I manage to see just one copy of each album in the Music folder, with just one copy of each song in it?

I figured it out.  In case anyone is interested it's like this;  I installed an app that is just called 'Battery'.  When I open it up, it shows (among other stuff) a small patch titled 'Notifications'.  By touching that patch I can toggle on or off an advice in the swipe down from the top of the screen that tells me the following information;

* what %age is left in the battery
* if it's charging, how long it will take to charge to 100%
* if the Nexus isn't charging, how many hours of use the battery has left in it.

I must have accidentally turned this function of the app off.  I've turned it back on and find it useful to have the above data in the swipedown.
