Problem while updating playlist

Hello, i am facing a problem when i update my playlist run time. what i need to do is load songs based on user preferences. when my current song is playing and i load new songs my current playing song stops in mobile. When i use clearPlaylist it doesnt work but if i remove songs from playlist then it works fine in web but song stops in mobile. I want to load new songs without halting the current playing song.
is there any way to start song from particular time ?? like play song from 1:10

here is my code ::

$timeout(function() {
angularPlayer.clearPlaylist(function(result){
angularPlayer.addTrack(song);
});
},0);

Please help.

You can use the angular event to set this.

$rootScope.$broadcast('track:progress', trackProgress);

trackProgress is the number of played progress. The range of it is from 0 to 100. Calculate the progress number, and use the function above to set the position you want.

A better solution may be not clear the song playing, use removeSong() to remove other songs. When the song is finished, remove it later.
