Should the song be of an exceptional length i.e. 6+ minutes, and sounds like it should really be 2 songs work I will contact you and negotiate an alternative arrangement. Mixing is a lengthy process at the best of times and long songs are especially difficult to get right and take time. I would advise that you purchase a 2 song “Single” package if your track is around or over this length and inform me on your additional notes with the order to avoid any issue or delay with your order.
