Band-in-a-Box "builds" a song different than what you might suspect. It "builds" the first few measures, begins to play the song and "builds" the remainder of the song as a background task while also continuing to play the song. In theory the BiaB media player should never catch up with BiaB's construction of the song. In practice the media player may catch up to the construction and when the media player catches up it pauses and waits for more construction to be completed. The process is comparable to watching a video over a slow internet connection. You download part of the video prior to viewing the video, you begin to watch the video while the remainder downloads in the background. If your viewing position catches up to the downloading position, viewing pauses.

One way around this is to use RealBand to play your songs. RealBand
completely 'builds" a song before the song begins to play.

Another way to minimize the issue is (BiaB 2016 build 438) to open "Options" > "Realtracks" to open the RealTracks Settings window and place a check mark for the settings "speed up generation of realtracks (disable on slow machines)" and "High Quality Tempo/Pitch Stretching (disable on slow machines)".

Another option is to render the songs to an (wav, MP3 or wma) audio file and use the media player of your choice the play the audio files.
