Place the option you suggested and it will be played before the song ends.
The idea is that the advertising is reproduced in a different window, it does it but it does not wait for the subject to end, the song continues to sound, the advertising ends and the same song continues.
What I want to do is that the advertising is reproduced in the independent window, to the reproduction window.
I managed to reproduce the advertising on the list in the independent window but I don't expect the song to end, it overlaps. attached capture. thanks and regards
