On 20 May 2022, the xPropaganda album titled The Heart Is Strange by Brücken, Freytag and Lipson was released in various formats by Universal Music on the ZTT imprint. Music journalist Daryl Easlea of Louder praised the album as "a compelling listen", remarking as well that its style sounded "exactly like it could have followed their old group’s debut". The album was a result of Claudia and Susanne approaching Stephen Lipson to ask him to write new songs with them that they could include in their live show. These were written and recorded during the lockdown and resulted in enough tracks to make an album. Their manager approached Universal with the album and gained a two-album deal. Michael Mertens had been approached to be involved in the song writing but declined.
