Hey wie heißt die Musik man hört sich nur ganz leicht bei 5:42 Minute?

At 5:42 minutes in the video you shared, you can hear music in the background. Unfortunately, it is not always possible to determine exactly what song it is. It could be background music created specifically for the video or a less well-known piece. To find out the exact music, you could try to contact and ask the creator of the video. Or you could try to identify the music with an app or website that offer music recognition services.
