Bro's b-day and spam

It's my younger brother's birthday today and I promised to spam people further with a song he wrote (collaboration with a friend of his). Sorry, it's in Greek, but foreigners can enjoy the music.
It's called Χωρίς Πληρωμή (Without Payment) and the two friend group Κούφια Καπέλα (Hollow Hats)

Tanjoubi omedetou, otouto!
