Poweramp is the only music app I’m using too. It’s just getting better with every update.
Gonna miss it.
I was gonna buy LG V20 for a music player. I still might. 
I just wish it was smaller. Given how limited the use of L5 is gonna be, maybe we should have that extra media device on us
Still dreaming of getting some nice mid range cans (my fav Sony MDR 1AM2) and pairing it with a phone with powerful DAC. Or getting the external one for more boost.
