Initially, for over a year, was awesome. Played perfectly. Last 2 updates though, changed something. It crashes within 1 to 2 songs. Deleted. Reinstalled. Worked a couple of times, then started crashing again. Deleted again. Not 100% sure if it's their update and/or Samsung's not playing, literally, well together. Too bad. It was a great non ad-intrusive app.

Crashs like these must not occur of course. Unfortunately yours are not reported, so I can't trace them. Please update to the latest version. Also try both play modes with and witout "Internal decoding". Do the crashs come with certain file types or settings?

Very nice minimalistic player. I use it for a long time on my PCs and really glad to have it on Android. Some notes from senior business analyst. :) 1. Most of Settings changes need restart to see it. It will be nice to avoid restart or at list force it automatically. 2. It will be nice to have Bookmarks icon in Controls bar. May be instead of Sort button, it less useful. 3. Control bar on the lock and notification screens is really missing. Many thanks for great utility.

Thank you for your feedback and for using 1by1. In Version 1.13 long press functions for the buttons have been added. You can access the bookmarks with the playlist button. Version 1.13 is avalable at the homepage. I've read about the lock screen issue some times. But whereever I test, I see the notification, and after dragging the three buttons.

Best music app ever. I've been using it in my computer for donkey's years, never bothering with any of those fancy apps/programs; I just see them as a waste of time. Great to now see this on Google. I initially had to download an earlier version from the 1by1 website. As I say, I've used nothing else and never will. Top marks to the developers for this. 5 stars, easily.
