I don't know if it is a bug, or my sloppy coding, but when I do:
[java]this.app.music = new AudioNode(assetManager, "music/hgfy.ogg", true);
first few seconds of music is played, then it is repeated (like in old broken vinyl record), before real music ends. It's kinda shame because my music files are kinda large (about 2-3 MB each) and loading one of them takes few seconds which would increase game's loading time. Streaming is good choice, but as I see, it doesn't blend well with music looping.
