For anyone wondering, Adriano Celentano isn't a one hit wonder, he's one of Italy's most celebrated artists who still goes on TV to this day.
He's got some cracking hits like Azzuro, which is a wistful song about missed connections and watching life go by. It's basically Italy's unofficial national anthem at this point (read: what Men At Work is to Australians). I recently found out that Die Toten Hosen did a half-decent cover of it too.
There's also this fun but somewhat baudy animation for one of his songs, featuring uh... sexy ducks? The song is cracking though, and the animation is amazing: Che T'aggia Di'
I noticed that in their info text shown to their users, they don't mention F-Droid. I wonder if google doesn't allow them to mention other stores as part of their "security" policies.
