Question – ShutEye®: Sleep Tracker, Sound Review

Question …after waking in the morning and going thru listening to the clips, on 2 of them there was some sort of rap music playing. Some song I’ve never heard. One was under talk and sleep and the other was under environment. Is this a mistake or an issue that the app could have had? Thank you.
