I love Poweramp! It's the best player forever! I believe that the homesick Winamp lovers loves Poweramp too =D
I bought it a few years ago, and I migrated to the alpha program for approximately one year ago. My resumed feedback by now is that it is best than the official version, which was already magnificent!
Because I'm a developer too, and since I become a alpha member, I believe that my feedback/bug report/feature request is very important, so I want to leave a feedback about the rating system, that functions perfectly, except when rating one star, it's inaccurate but not impossible to do.
I'm using a Samsung Galaxy S7 (flat edition) most time in mode landscape.
If you want more information, call me please.
Thanks a lot! Best regards!
