Other voices took over my bluetooth speaker

I came across this post after searching "voices coming through bluetooth speaker" because last night I had my iphone 6s connected to my bluetooth speaker listening to music off the Tidal app. The music randomly stopped playing in the middle of a song, and a few male voices came over the speaker. Sounded like they were having a strange conversation. One guy kept repeating the same vulgar thing almost like a subliminal message had come to life. It lasted less than a minute, then the music came back on. During the time, my phone still showed I was connected to the speaker, and the song didn't ever show that it was paused. Very strange! It would be nice to know what that possibly could have been.
