Answer 1

you can check the playing status, if it is playing you have to stop the player and reset the contents and issue the command Play.

if (mplayer.isPlaying()) {
    mp.stop();
}
mplayer.reset();
mplayer.setDataSource(abs_filepath);//set the path
mplayer.prepare();
mplayer.start();

above a sample code

Answer 2

Don't you want a check like this:

if (mplayer != null && mplayer.isPlaying()) {
    mplayer.stop();
}

at some point before you start your next song?
