Almost 50 years after its release, the song "Guten Morgen, Sonnenschein" (Quand tu chantes) had a second life. This time, at an international level, by becoming a hit on listening platforms and social networks. This, following the launch of the mini-series "Cassandra" on February 6, 2025 on Netflix. In this thriller, the virtual assistant of Germany's first connected home wakes up its occupants with this old success. After two weeks, it was announced that the serie had surpassed 17 million views. Cultural commentators were unanimous; everyone who watched it had the song stuck in their head and searched for it online. On Deezer, the number of plays increased by 88% worldwide. On iTunes, it was number one in Poland and Hungary, and number two in the Czech Republic. On TikTok, it was used in nearly 23,000 videos. At the same time, "Guten Morgen, Sonnenschein" was her most popular track on Spotify and had reached 36,7 million streams. To this must be added that the main video on YouTube has been viewed nearly 15 million times. Reached by phone, Nana said she was touched that one of her songs had become popular again and that the younger generation was discovering her.

To continue with this unexpected triumph, it seems interesting to point out that from now on, music companies refer to the statistics of music streaming platforms when it comes to highlighting the work of their creators. This is what Universal Germany did recently by awarding her a gold disc for this song that dates back several decades. In addition to the 50,000 copies of the original single, Internet traffic linked to "Guten Morgen, Sonnenschein" was equivalent to 200,000 sales. This therefore represents a new era for Nana who was used to being rewarded for the physical sales of her records. And, with her extensive repertoire, we can bet that it will not be limited to one title. In the meantime, let's continue to follow the wonderful success of "Cassandra" to see how beneficial it is for Nana.
