Honestly, Poweramp is the main reason I have stayed on android. I have made over 10 musicians install it especially for the Bass. Nothing matches it., NOTHING and trust me I have tried over 6 of them. But now I am compelled to move to iPhone. I am even considering having 2 phones, one for music and one communication. If only we could get one for iPhone even if you charged 10x the amount, I would still buy it.
Please consider sir. I am a developer myself, I know how hard it can be, but just try please.
