The weather is turning cold and uncomfortable outside, but with her single "Mein Herz lacht" (My Heart Smiles), Kati Sommer warms listeners' hearts like a ray of sunshine and brings good vibes to rainy days with this feel-good song. It's often the little things in life that can make a big difference. For example, just the thought of a loved one can be enough to save the day and keep you from drowning in melancholy. Kati Sommer takes us into her positive world of thoughts with this song and offers "Mein Herz lacht" as the introduction to her current album "Dreamworlds", a musically diverse collection of seven German and seven English tracks, created together with producer and guitarist Ralf Rudnik.
