Discovered Inline Music Player. Somehow it's based on foobar 2000. Free version doesn't have time limit but have disabled some features (not really necessary like audiofx, album art downloader etc). Loading takes ~3 seconds but UI is very responsible, track loading & rewind is fast, also it sounds very different from other players.
Installation file weights 648 KB, installed - 1.3 MB, takes 11 MB of RAM when playing files, eats CPU less than BASS-based players (freeamp, AIMP).
Unfortunately just like 1by1 it plays only formats that your device/firmware/stock player supports (no flac support for Android 2.3.6)
