I'm from Poland and my favorite songs are Mata - "Patointeligencja" and Yung Adisz - "Witam w Podziemiach" 🙂 Hope you like it! And I know, my preferences are a bit weird... but I don't care! I love these songs so much, they are kinda emotional.
Here's one of my favorites. It's called: "Un giorno mi dirai" by Stadio, the genre is pop rock. It's a very emotional song, it moves me every time. Also the lyrics are very touching.
