Hi all! I've been quite happy with Poweramp's performance, except for one detail: the license scheme is absurd. The unlocker app will re-run its license checks even after passing them, at seemingly random intervals. Since I spend a lot of my time offline, this means it will eventually run its license check while there is no internet and Poweramp will refuse to work. This has happened to me 4 times in the last 6 months. Emails to Poweramp's support remain unanswered, and reviews on the Play Store show many users complaining about this, even after several updates. I'm about to ditch this app... it's no fun to spend 8 hours (as I did today) surveying several hectares of hot, humid, bug-infested forest, only to have Poweramp cut my music 1 hour into the job. Enough of the rant, but thanks for listening! I'm looking for a replacement audio app. I don't like Sony's Walkman app because it won't let me play folders. I'm testing Mixzing Audio Player, but I found an interesting option: Neutron Music Player. It claims to be very advanced, and I tend to agree since I can't make sense of a lot of its features and options. Settings are highly technical, but this is not as good as it may seem, since right out of the box the app may not yield adequate audio quality. On my Z1 audio was clearly distorted, so I had to RTFM and activate the "automatic gain protection" feature. I'm still testing it, but 5 days (duration of the trial app) is not enough to run through all the options. Has anyone here tried this player? If not, I'm looking for other options. What other audio player can play folders, has good equalizer and strong bass response, and uses the regular Google Play license scheme? Thanks!
