I use my iPhone and wireless headphones to play fb videos at the gym. I would love to add in workout music for some of the videos I have done many times now. Has anyone figured out how to get music to play on a phone (Spotify, the Apple Music app, YouTube or other) while still playing the videos? I'd still really like to follow along with videos visually...I don't think it would be fun to just follow the print outs.

Thanks for any tips!
