Answer 1

You have to do more than remove the header to make an mp3 unplayable. If you take my other answer to your question and apply it to the whole file there should be no way it can be played:

RandomAccessFile raf = new RandomAccessFile("input.mp3", "rw");
byte[] buf = new byte[65536];
long pos = 0;
int len;
Random random = new Random(34);
while ((len = raf.read(buf)) != -1) {
    for (int i = 0; i < len; i++) {
        buf[i] ^= random.nextInt();
    }
    raf.seek(pos);
    raf.write(buf);
    pos = raf.getFilePointer();
}
raf.close();

This will XOR every byte in the file. The only reason I suggested in the other answer to only do the first 64k was for performance since you’re on an Android device. For me that made it unplayable on my desktop. If doing the whole file doesn’t work for you then I suspect you’re doing something else wrong. There no way it’ll play the original music if every byte is changed like this. You can run this again to undo it and make the mp3 playable again.
