Can Zoom Music be streamed on two different meetings at the same time?

The participant using the Music app must be the only participant sharing in a given meeting, as multiple simultaneous shares will prevent the music from being heard by all. 

Running 2 separate meetings at the same time should be done on 2 separate devices.

Since 2 separate meetings also require separate licenses for each meeting then each meeting can use the music app. This music is properly licensed for playback to all participants and can be recorded on Zoom. Use of other music outside this app may constitute copyright infringement.
