Also keep in mind, that many DSP's like Beatport, iTunes, and Spotify have cut-off periods during holiday seasons, during which time they have limited resources or are not accepting any uploads during that time. You can still schedule your releases to come out during those times, but there may be a delay in processing any new uploads or updates. Some of them may be out of the office entirely and will not be around to make changes or process new uploads. Therefore, it is important to plan your release schedule accordingly.
