Radebeul is a town in Saxony near Dresden, and Kötschenbroda is one of its districts, so the pairing will be familiar to people who travel through the area or follow local German content. Online, short place-name clips like this are often shared as soundboard sounds because they are instantly recognisable, easy to drop into a video, and carry a strong sense of place in only a few seconds. Their appeal does not depend on a wider trend: the names themselves do the work, especially for viewers with a connection to the region.
