Galaxy S5 :: How To Set Poweramp As Default Music Player

And set it up so that when I plug in my headphones and hit play on the remote, the music starts playing. On my S3, it was really easy. I just installed the app, and when asked if I wanted to set it as my default music player, I just said yes, and presto! Poweramp all day every day. I'd plug in my headphones and it was good to go. But on my S5, there doesn't seem to be any way to set a default music player. If I go into my application manager and go to Poweramp, under "Launch by default", It says "No defaults set", but there is no way to press the "Clear defaults" button because it isn't highlighted. It's just faded.

This is the case for Google Play Music, and the default S5 music player app as well. When I go to "Default applications" in the settings, under "Set Defaults", there are only 2 options: "Home" (TouchWiz Home), and "Messages", but there doesn't appear to be any way from here to set any new default apps such as my music player of choice. The worst part is, maybe 4 out of 10 times, when I plug in my headphones and click the play button on the remote, Poweramp will start and a song will start to play, but the other 6 times, I'll click play and nothing will happen and I have to unlock my phone and manually press play on the Poweramp widget on one of my home screens. I just want to plug in my headphones and have it work consistently every time like it did on my S3.
